Hygrometers and Humidity Measurement Instruments - (604 companies)...or impedance style sensors, a material absorbs moisture, which changes its resistivity or impedance. In strain gage instruments, a material absorbs water, expands and is measured with a strain gage. Psychrometers, often called wet/dry bulbs, measure...Form FactorVariables MeasuredCompensation -
Aspirators - (11 companies)Aspirators are suction devices used to remove mucus and other bodily fluids from a patient. Aspirators are medical devices commonly used to remove bodily fluids, such as mucus, from a patient via a vacuum mechanism. The aspirator's portability lends...
-
Weather Instruments - (328 companies)Weather instruments are designed to measure one or multiple components of weather including wind speed and direction, rain or snow fall, solar radiation, temperature, pressure and humidity. -
Gas Flares - (30 companies)Gas flares, alternatively known as a flare stacks, are used to eliminate waste gas, which is released via pressure relief valve when needed to ease the strain on equipment.
-
Hall Effect Proximity Sensors - (131 companies)Hall effect proximity sensors are used to detect the proximity, presence or absence of a magnetic object using a critical distance. -
Syringes and Needles - (225 companies)Syringes utilize a cylinder and plunger for precise delivery of liquids or gases in analytical, medical, pharmaceutical or biotechnology applications. Many times needles are included with the syringe.
-
Thermistors - (331 companies)Thermistors are thermally-sensitive devices whose electrical resistance varies with temperature. Unlike RTDs and thermocouples, thermistors do not have standards associated with their resistance vs. temperature characteristics or curves.
-
Humidity Controllers - (128 companies)Humidity controllers monitor and maintain proper humidity levels in environmental test applications, food storage areas, and electronic equipment rooms.
-
Vacuum Gauges and Instruments - (219 companies)Vacuum gauges are devices for measuring vacuum or sub-atmospheric pressures.
-
Air Purifiers - (284 companies)Air purifiers re-circulate, filter and purify air for process and environmental applications.

Technologies for Next-Gen Electronic Pipettes Innovative Motion Technologies for Next-Gen Electronic Pipettes. A pipette is a laboratory tool used in chemistry and biology to aspirate and dispense measured volumes of liquid. In molecular biology and analytical chemistry, electronic pipettes ensure accurate and repeatable delivery of samples and reagents while reducing the risk of repetitive-strain injury. Whether designing a single or multi-channel electronic pipette, size, weight, and ergonomics are critical factors for design engineers... (read more)Browse DC Motors Datasheets for Portescap -

Monitoring Combustible Gases in Kilns A new white paper by Control Instruments, "Monitoring Combustible Gases in Kilns," discusses the hurdles involved with monitoring combustible gas concentrations for safety and key points to consider. Heating all sample-wetted parts of the analyzer and sampling system to 250 C will prevent condensation. The sample stays intact. The measurement includes all combustible vapors. Sample pumps cannot provide the same level of reliability as an aspirated sampling system and should be avoided... (read more)Browse Combustion Analyzers Datasheets for Control Instruments Corp. -

Next-Level Pipetting: ZEUS X1 Delivers that utilizes a piston to aspirate liquid into a disposable tip. As the piston moves up, the air pressure in the tip decreases, allowing the sample to be pushed into the disposable tip by atmospheric pressure. With the introduction of ZEUS X1, Hamilton takes air displacement pipetting to the next level. Unlike traditional liquid-filled air displacement systems, this new device incorporates a solid-state piston, resulting in improved performance and reduced maintenance requirements. One...

Unmatched Accuracy and Precision was developed. For these sensitive applications, the sample is aspirated into a disposable plastic tip which is thrown away between each sample, eliminating any chance for carryover. Applications that benefit from the DTHP include: Forensics --for some applications regulatory considerations make disposable tips the preferred option. Sterile samples --sterile disposable tips can be used to avoid transferring contamination between sample vessels. DNA amplification --for applications where a single...

PrevEx Flammability Analyzer Unmatched Safety a sensor. With condensation comes clogging, fouling, and poisoning, which restricts the sample flow to the analyzer, removing important elements from the sample stream. This results in inaccurate readings. PrevEx has a corrosion resistant, heated sample train through which the sample is delivered. The heat eliminates condensation and withstands corrosive elements leaving an accurate representation of the process. The PrevEx analyzer collects the sample using an air aspirator, driven by compressed air... (read more)Browse Gas Instruments Datasheets for Control Instruments Corp.
