Temperature instruments use contact or noncontact methods to measure temperature.

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

Temperature indicators and temperature instruments are designed for temperature monitoring and analysis.

Humidity controllers monitor and maintain proper humidity levels in environmental test applications, food storage areas, and electronic equipment rooms

Temperature probes are used in various temperature sensing applications.

Specialty industrial process controllers are used in unlisted, specialized or proprietary applications

Programmable automation controller (PAC) modules are add-on devices that perform a specific control function in PAC systems
