Time Electronics 1090 Portable Process Calibrator
This high specification process calibrator is lightweight, portable, battery or mains powered calibration unit and can be used to source and measure thermocouples, PT100s, μV, mV and mA.
When used with thermocouples, the 1090 can be used to measure/simulate temperature (in both Celsius and Fahrenheit) plus mV characteristics of type J, K, T, R, S, B, N and E type thermocoples. It also includes the ability to carry out PT100 measurement and simulations (based on 0.3850 alpha probe standard) between a range of -200 to 700°C.
The final measurement/simulation mode on this device enables it to measure 0 to ±30mV and 0 to ±60mA and source from 0 to ±80mV and 0 to ±80mA.
This calibration device also comes with cold junction compensation, meaning it can be operated with ot without internal cold junction compensation. Other additional features include a 24V process loop drive mode, inching (incrementing/decrementing) and built-in memory.
