1090 Portable Process Calibrator

The 1090 is a precision portable process calibrator that combines source and measurement functions for thermocouples, Pt100s, µV, mV & mA. It is a multifunction instrument that combines accuracy and durability with simple operation, making it ideal for process plant applications and field testing work.

Thermocouple Measurement and Simulation: Measure and simulate the temperature and mV characteristics of J, K, T, R, S, B, N and E thermocouples. The 1090 can be operated with or without internal cold junction compensation. 

Pt100 Measurement and Simulation: Based on 0.3850 alpha probe standard. Range is -200 °C to 700 °C.

Measurement and Source (µV, mV, and mA): Measurement ranges are 0 to ± 30 mV and 0 to ± 60 mA. Source ranges are 0 to ± 80 mV and 0 to 80 mA.

Temperature Units Selection: The display can be easily changed from °C to °F. The equivalent µV (thermocouples) and ohms (Pt100) can also be shown. 

24 V Process Loop Drive Mode: A process loop can be driven at 24 V and up to 60 mA by selecting the ‘Milliamp Source’ mode and setting it at 60 mA (or a lower level if required).
