Full Featured Calibrator


RADICAL is a precision instrument used either as a temperature indicator with input from RTD sensors and thermocouples or to calibrate 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). The calibrator's microcontroller-based design incorporates a highly stable reference, a high-resolution Analog-to-Digital converter, switching circuitry and other specialized proprietary electronics. An LCD shows measured parameters in Celsius or Fahrenheit, peak and trough values and bar-graphs amongst other functions. RADICAL generates a 24V loop supply to power a 2-wire transmitter or similar instruments that lack their own power-source. When used as a calibrator in source mode, you may manually step up the signal to your instrument or set an automatic ramp function. Highly portable, RADICAL houses a powerful Lithium-ion rechargeable battery that keeps it functioning up to 14 hours on a single charge. The calibrator features auto-shutdown to conserve battery-life as well as visual alerts for low battery levels. A cost-efficient, portable version of RADICAL can be found in MICROCAL.
