Air velocity flow sensors measure air velocity or volume flow using insertion probes or capture hoods.
|
|
Conductivity meters, dissolved solids meters, and resistivity meters are analytical instruments that measure the conductivity, dissolved solids, and/or resistivity of a liquid sample.

|
Data acquisition is the digitizing and processing of multiple sensor or signal inputs for the purpose of monitoring, analyzing and/or controlling systems and processes. Signal conditioning includes the amplification, filtering, converting, and other processes required to make sensor output suitable for rereading by computer boards.
|
|
Data loggers and data recorders acquire digital data from sensors and other signals. They are primarily used to store data for subsequent downloads to a host PC, but may also include real-time features such as monitors and alarms.
|
|
Dial thermometers are bimetal or bi-metallic, liquid or gas-filled, and vapor-tension-based. These devices display temperatures in Fahrenheit, Celsius, or both.
|
|
Digital ammeters are instruments that measure current flow in amperes and display current levels on a digital display. These devices provide information about current draw and current continuity in order to help users troubleshoot erratic loads and trends
|
|
Digital multimeters (or multi-meters) are used to measure electrical quantities such as voltage, current, resistance, frequency, temperature, capacitance, and time period measurements.
|
|
Digital pressure gauges use electronic components to convert applied pressure into usable signals. The gauge readout has a digital numerical display.
|
|
Digital thermometers are portable temperature sensing devices that have permanent probes and a digital display.
|
|
Digital voltmeters are instruments that measure voltage or voltage drop in a circuit. They use solid-state components and display values digitally.
|
|
Fiberscopes are inspection tools with flexible optical tubes for interior inspection of holes, bores, and cavities.
|
|
Gas and air instruments detect, monitor or analyze gases present in an environment.
|
|
Humidity measurement instruments test for absolute humidity, relative humidity, or dew point in air.
|
|
Humidity transmitters provide electrical outputs that are proportional to humidity inputs. They measure variables such as relative humidity, absolute humidity, specific humidity, moisture content, dew point, temperature, and pressure.
|
|
Manifolds and manifold systems are fluid-distribution devices. They range from simple supply chambers with several outlets to multi-chambered flow control units including integral valves and interfaces to electronic networks.
|
|
Moisture meters are used to measure the moisture content in bulk solids, liquids and gases.
|
|
Noncontact infrared temperature sensors absorb ambient infrared (IR) radiation given off by a heated surface. They are used in applications where direct temperature measurement is not possible.
|
|
pH and oxidation reduction potential (ORP) instruments measure or monitor pH (relative concentration of hydrogen ions [H+] in a solution) as well as ORP.
|
|
Pressure gauges are used for a variety of industrial and application-specific pressure monitoring applications. Uses include visual monitoring of air and gas pressure for compressors, vacuum equipment, process lines and specialty tank applications such as medical gas cylinders and fire extinguishers.
|
|
Pressure instruments are used to measure, monitor, record, transmit or control pressure.
|
|
Sensor transmitters are measurement or signal conditioning packages that provide a standard, calibrated output from a sensor or transducer in the form of a current loop output (e.g., 4-20 mA).
|
|
Signal conditioning products provide amplification, filtering, converting, and other processes required to make sensor output suitable for reading by computer boards.
|
|
Signal converters contain inputs for one type of signal and outputs of another. Features can also include filtering and amplification or attenuation.
|
|
Sound level meters and noise dosimeters are used in sound and noise analysis. Applications include industrial safety, traffic noise studies, and scientific noise measurement.
|
|
Specialty or proprietary products related to environmental sensors and instruments.
|
|
Stroboscope instruments are used for inspection and observation of moving parts by freezing or slowing down the action of an object.
|
|
Tachometers are used to measure the velocity of a rotating object. They operate on the principle that a driven motor (i.e., a motor operated as a generator) produces a voltage that is proportional to the angular velocity of the motor shaft.
|
|
Temperature indicators and temperature instruments are designed for temperature monitoring and analysis. These devices either come equipped with an integral sensor, or require sensor input.
|
|
Temperature instruments use contact or noncontact methods to measure temperature. Products include dial, digital, industrial and laboratory thermometers; temperature probes, indicators, and sensors; RTD elements and transmitters; and thermistors, thermocouples, thermopiles, and thermal switches.
|
|
Temperature sensors are measurement devices that infer temperature by sensing some physical characteristic (i.e. resistance, emf or thermal radiation).
|
|
Temperature signal conditioners accept outputs from temperature measurement devices such as resistance temperature detectors (RTDs), thermocouples, and thermistors. They then filter, amplify, and/or convert these outputs to digital signals, or to levels suitable for digitization.
