Portable documenting calibrator
A new standard for portable multifunction calibrators
The Druck TRX II portable documenting calibrator is the culmination of many years of combined field experience with the Druck and Unomat series of calibrators.
This one self-contained, battery powered package 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 which 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. Connectors for source and measure are kept separate and a 24V output is provided for loop power.
The TRX II’s extensive measurement capabilities can include pressure measurement by connecting Druck pressure sensors which have been digitally characterized to give high accuracy.
This highly accurate and easy to use documenting calibrator provides improved data quality and quicker calibration time since data can be uploaded and downloaded via the PCMCIA card or the RS232 interface.

Simple to operate
The combined Druck and Unomat knowledge of customer needs, and innovative design, results in a high performance, yet easy to operate, multi-function documenting calibrator.
The key to the simple operation of the TRX II is the structured menu. Input and output readings are displayed simultaneously for test modes such as T-I and P-I, allowing quick comparison of the values. Used in conjunction with Linkpak-W calibration software, or Intecal-W database software, the TRX II will perform automatic calibrations from predefined procedures, calculating and reporting errors to the operator and storing the results on a PCMCIA card. This intuitive approach, whether used manually or automatically, ensures correct set up for the job at hand and improves working efficiency and data accuracy.
The TRX II provides simple and flexible data transfer to fit in with most working practices. Information can be reviewed on screen or transferred to and from the TRX II using the RS 232 interface. Alternatively, without docking the instrument to a PC, data can be transferred by exchanging PCMCIA cards.
The operating system works in several languages and provides scaling, step and ramp features for calibration and maintenance. The TRX II, which includes extensive self-test routines, can be relied upon time and time again for field calibration in extreme conditions.
