Universal Calibrator

Universal Portable Calibrator is a precision instrument used either as a temperature indicator with input from RTD sensors and thermocouples or a calibrator for other process instruments. It can be used in any of 3 modes: measure, source or simultaneous, which combines the first two. It handles a wide range of process inputs - RTDs, thermocouples, mV and mA linear input and resistance (ohms). Built of a microprocessor-based closed-loop design, the calibrator's programmed output is continuously compared to a highly stable reference and automatically corrected for errors. It achieves a very high accuracy with a possible error of only 0.02% of the full-scale value. Powered by a Ni-Cad battery, MICROCAL is extremely portable and lasts up to 8 hours of constant use on a single charge. It weighs a mere 1.5 kg and takes a little less than 4000 cc of space. The calibrator directly displays thermocouple and RTD inputs in Celsius or Fahrenheit units. MICROCAL performs automatic or manual electronic cold-junction compensation for thermocouples to maintain a high-accuracy even in the case of thermocouples connected via extension wires.
