Time Electronics have a range of portable process calibration instruments for field and laboratory use. Products include temperature calibrators and simulators for RTD and Pt100 applications, and loop calibrators. These calibrators are commonly used for on-site field instrumentation testing of transmitters, transducers and sensors.

Process loop calibrators provide users with an accurate and reliable solution for maintaining and calibrating 4 to 20 mA loops. They allow users to troubleshoot and test process parameters with source and measurement of mA and voltage. For temperature, in addition to the calibrators shown below we have resistance decade boxes that can be used for Pt100 simulation.
