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

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

Instrument calibration services test equipment and calibrate them to various standards.  

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.

Density and specific gravity instruments are meters used to determine density and specific gravity

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

Digital thermometers are portable temperature sensing devices that have permanent probes and a digital display

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

Flow computers, totalizers, and rate indicators integrate the functions of flow and temperature measurement, computation, data acquisition, input / output (I/O) standardization, and closed loop control. They require external sensor inputs and may be used as local rate indicators

pH and oxidation reduction potential (ORP) instruments measure or monitor pH (relative concentration of hydrogen ions [H+] in a solution) as well as ORP

Vibration instruments are used for measuring, displaying and analyzing vibration. Typically these instruments comprise a transducer, data acquisition and either a local display or some sort of output to a computer or another instrument

Calibration instruments use electrical signals or physical quantities to calibrate sensors and meters. Devices that produce electrical signals can serve as precise meters for sensor calibration, or send output signals to other devices

Solar radiation instruments measure the spectral range of radiation, including global solar radiation (sun + sky), net radiation (incoming solar - reflected solar) and the photosynthetic light spectrum
