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 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 sensors are measurement devices that infer temperature by sensing some physical characteristic (i.e. resistance, emf or thermal radiation

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

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

Temperature probes are used in various temperature sensing applications. Technology options include thermocouple, RTD, thermistor and solid state style probes

Temperature controllers accept inputs from temperature sensors or thermometers, and then output a control signal to keep the temperature at the desired level

Humidity measurement instruments test for absolute humidity, relative humidity, or dew point in air

Thermocouple temperature probes are bimetallic style probes used for various temperature sensing applications

Environmental test chambers and rooms are used to ensure the reliability of industrial products, especially electronic items, through prolonged exposure to one or more environmental parameters.

Thermistor temperature probes sense temperature by using thermistors, devices made of semiconductor materials which exhibit a large change in resistance for a small change in temperature

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

Welding machines and joining machines include all manner of devices used for welding, brazing and soldering.

Non-destructive testing (NDT) equipment is used to detect, inspect, and measure flaws, bond integrity, and other material conditions without permanently altering or destroying the examined part or product

Temperature sensor chips are semiconductor dies or packages that have built-in temperature sensors
