The Unomat TRX II portable documenting calibrator is a self-contained unit, battery powered, simulates and
measures RTD’s, thermocouples and resistance, as well as sourcing and reading milliamps, millivolts, volts and frequency. The rugged design includes an impact resistant enclosure that is fastened to the carrying case for convenience and safety. Dedicated alphanumeric and documenting keypads surround a large LCD panel with dual readout and backlight (not I.S. version). The source and measure connectors are kept separate and a 24V (12V I.S. version) output is provided for loop power.

The TRX II’s extensive measurement capabilities can include pressure measurement by connecting Druck pressure sensors that have been digitally characterised to give high accuracy.
The Intrinsically Safe version is a complete maintenance tool and portable calibration standard, for process instruments and control loops in hazardous ’Zoned’ areas. Certified to CENELEC standards, the TRX II I.S. can reduce the response time to breakdowns and emergencies by removing the need for ’Hot Permits’ and gas detection equipment. It gives peace of mind to all those responsible for safety in hazardous areas.
This highly accurate and easy to use documenting calibrator gives improved data quality and quicker calibration time since data can be uploaded and downloaded via the PCMCIA card (not I.S. version) or the RS232 interface.
