All new! The Masterflex® L/S® Precision Variable-Speed Console Drive features a digital display that ensures accuracy and repeatability in fluid metering applications. This new model will be displayed at the Cole-Parmer® booth at PITTCON, March 13–March 18.
The drive offers precise speed control and digital display of rpm to confirm speed setting at a glance. A reversible motor enables users to purge tubing before or after pumping; LED indicators confirm motor direction. Users achieve flow rates of 0.6 to 3400 mL/min with Masterflex L/S pump tubing. A powerful motor will drive two or four pump heads for increased flow rates and for multichannel applications. The membrane keypad offers easy up-front control of speed, direction, and start/stop. Drives also offer remote control capability via 4 to 20 mA or 0 to 10 V input signal.
Emissivity is a term representing a material’s ability to emit thermal radiation. Each material has a different emissivity. A material’s emissivity can range from a theoretical 0.00 (completely not-emitting) to an equally-theoretical 1.00 (completely emitting); the emissivity often varies with temperature. Silver is an example of a substance with low emissivity (emissivity coefficient of .02), whereas asphalt has a high emissivity coefficient of 0.98.
To take a temperature measurement of an object, the thermographer will refer to the emissivity table to choose the emissivity value of the object, which is then entered into the camera. The camera’s algorithm will correct the temperature by using the emissivity to calculate a temperature that more closely matches the actual contact temperature of the object.

Thermal imagers are ideal for use in applications where a visual indication of temperature variation may be helpful, such as troubleshooting electrical systems and machinery or doing a home energy audit. Thermal imaging is a non-contact technology that measures infrared wavelengths to determine temperatures from a safe distance. A thermal imager displays an image using different colors to represent different temperatures. Extech and Flir thermal imagers are fully radiometric which means they measure and store temperatures at every point in the image.The data can then be analyzed. With the highest accuracy for this class of thermal imagers at 2%, these imagers are perfect for identifying hot spots or a rise in temperature which often indicates that a problem exists or a failure could be imminent.
Cole-Parmer offers a wide assortment of thermal imaging cameras with a variety of features depending on your particular application or budget.
Although Infrared thermography, or thermal imaging use has increased recently within commercial and industrial applications, it has a long history beginning in the 1800s when Sir William Herschel discovered infrared.
Flir i3 Entry Level Thermal Imagers
Timeline:
Astronomer Sir William Herschel discovered infrared in 1800
1950-1960 Single Element Detectors (Line Images)
1970 Philips and English Electronic Valve (EEV) developed Pryo-Electric tube. First Naval Thermal Imager used by the Royal Navy for shipboard firefighting.
1978 Raytheon patented ferroelectric infrared detectors using on Barium Strontium Titanate (BST)
Late 1980’s Microbolometer technology developed.
How it works:
Thermal imaging cameras convert the energy in the infrared wavelength (9,000 to 14,000 nanometers) into a visible light display, making it possible to view the environment without visible illumination. The thermal imaging camera performs a series of mathematical algorithms and builds a visible picture, usually in a JPG format. The image shows the viewer an approximation of the temperature at which the object is operating rather than detecting the actual temperature.
All objects above absolute zero emit thermal infrared energy, so thermal cameras can passively see all objects, regardless of ambient light. However, most thermal cameras only see objects warmer than -50°C. The amount of radiation emitted by an object increases with temperature; therefore, thermography allows one to see variations in temperature.
If the object is radiating at a higher temperature than its surroundings, then power transfer will be taking place and power will be radiating from warm to cold following the principle stated in the Second Law of Thermodynamics. So if there is a cool area in the thermogram, that object will be absorbing the radiation emitted by the warm object. The ability of both objects to emit or absorb this radiation is called emissivity.

If you live in the Eastern or Midwestern United States, there’s no need to guess how cold it is outside this winter ―the new H-B Instrument Enviro-Safe® Nonhazardous Glass Thermometers available from Cole-Parmer will confirm that.
H-B Instrument Enviro-Safe® Thermometer
Cole-Parmer is proud to present these new Earth-friendly “green” thermometers certified as 100% nontoxic, nonhazardous, and biodegradable. These accurate and safe thermometers offer the same accuracy as mercury thermometers without the hazards. They are ideal for use in laboratories, universities, food/beverage, environmental, wastewater, and many other general-purpose applications where the presence of mercury or other hazardous liquids is not desired.
All Enviro-Safe glass thermometers contain an environmentally friendly non-mercury liquid that is 100% certified as nontoxic, nonhazardous, and fully biodegradable. In case of breakage, the liquid can be cleaned up easily with soap and water. These thermometers also have recyclable packaging, an antiroll fitting, individual serial numbers, and a statement of accuracy.
So, what’s so bad about mercury thermometers, anyway?
Mercury thermometers are harmful to both the environment and your personal health. In fact, Mercury is toxic to humans and wildlife. If a mercury thermometer breaks and is not properly disposed of, tiny droplets of mercury can evaporate within the environment over time. When mercury vapor enters the bloodstream through inhalation, brain damage, spinal cord, kidney, and liver damage may occur in time.
Additionally, improperly disposing of mercury from thermometers can contaminate lakes and streams. Mercury may accumulate in the bodies of fish and other wildlife and, through natural processes, converts this mercury into methyl mercury, which is harmful to humans when consumed.

Did you know Monday, November 8, was X-ray Day? The X-ray was discovered in 1895, purely by accident. Wilhelm Röntgen, a German physicist, was experimenting with electron beams on a gas discharge tube. When the electron beam was on, a nearby fluorescent screen started to glow. Thus began the journey of a technology that is used in medical imaging, dentistry, astronomy, research, and even laser bursts.
Because X-rays pass through muscles and other soft tissue and stop at dense materials, doctors can identify broken bones and cancers growing in the body. Electromagnetic radiation is also used in communication systems and in neutron activation analysis, allowing the identification of elements in a material.
While radiation provides many benefits to the scientific world, high levels of radiation in the environment and in food handling can be hazardous. Cole-Parmer offers Radiation Alert Analog Detectorsto monitor radiation. These general-purpose detectors are available with uncompensated halogen-quenched sensors for measuring alpha, beta, gamma, and X-ray radiation; select meters have energy-compensated sensors for increased sensitivity to gamma and X-ray radiation.
All models are factory-calibrated to pulse generator and can be calibrated to ANSI standards by any certified lab. Anti-saturation circuit is good to at least 100 times the maximum reading in the highest range. No special probes are required.

On this week 53 years ago, Sputnik I successfully launched and changed history. As the world’s first artificial satellite, the launch signaled the beginning of new developments in the military, politics, technology, and science. It also led to the creation of the National Aeronautics and Space Administration (NASA).
For skywatchers, this anniversary is another reason to turn our eyes to the skies. To do so, a versatile telescope is necessary. Cole-Parmer offers a series of microscope/telescope combinations that allow users to magnify up close or view objects―including the moon―at a distance.
Constructed of durable aluminum and plastic, the scope has a 6° field of view. Its lens magnifies up to 10x as a telescope. The microscope/telescope combination includes a neck strap, micro lens stand, hard carrying case, and carrying strap. To use, simply unscrew the micro lens and stand and use the monocular as a telescope.
Because of its versatility, it can also be used for inspecting items up-close. As a microscope, it magnifies objects by 45x.
Whenever there is sufficient voltage in an electrical system and a path to ground, an electric arc or arc flash can occur. Arc flashes can be quite dangerous and may cause extensive damage to electrical components, fires, or personal injury. A typical arc flash may be insignificant, yet some can produce severe explosions and cause injury to those nearby .
It is extremely important when working with electrical equipment to take appropriate precautionary measures such as de-energizing electrical equipment and, of course, wearing personal protective equipment (PPE). Arc Flash PPE materials are tested for their arc rating, which indicates the maximum incident energy resistance of that material. Arc rating is typically expressed as small calories of heat energy per square centimeter (cal/cm2). Tests to determine arc rating are available in ASTM F1506-10Standard Performance Specification for Flame Resistant Textile Materials for Wearing Apparel for Use by Electrical Workers Exposed to Momentary Electric Arc and Related Thermal Hazards.
While PPE is important, the downside is that it provides protection after an arc flash incident has already occurred, and therefore should be viewed as the last line of protection. Reducing the frequency and severity of incidents should be the first option and can be achieved through a complete arc flash hazard assessment, along with implementing technology such as high resistance grounding (proven to reduce the frequency and severity of incidents).
In addition to appropriate PPE, consider working outside the hazard zone. One product offered by Cole-Parmer that allows taking readings outside the hazard area is the Fluke 233 Remote Display Multimeter.
Fluke 233 Remote Display Multimeter
The 233 is a rugged digital multimeter (DMM) that can be used just like any other DMM in the field. Yet, it also offers the ability to safely take readings while energizing and de-energizing equipment. How many times have you had to place a meter in a precarious— and possibly unsafe position—in order to observe the readout? The wireless technology greatly reduces these risks.
A common practice in the electrical field is for someone to hold the meter as the technician reaches inside the control panel or switchgear to place the test leads for the measurement. This “meter reader” then is exposed to virtually the same shock and arc-flash hazards as the individual placing the test leads. With the 233’s detachable head, this “meter reader” can now stand safely outside of the Flash Protection Boundary while recording readings. Another issue― the inconvenience of taking readings while dressed out for Hazard Risk CAT III or CAT IV―also finds a remedy By enabling the person observing the meter reading to stand outside of the boundaries stated above, protective clothing requirements can most likely be reduced to a lower Hazard Risk Category..
Cole-Parmer cares about safety and offers a wide selection of safety apparel and electrical equipment to provide protection against arc flashes.
