Divya process instruments manufactures dry temperature calibrator. It is a must for calibration of rtds, thermocouples, temperature gauges and temperature switches from 50 to 650°c. A dry temperature calibrator uses a copper aluminium alloy block as the heated medium and a wire-wound rtd element as a sensing device. Use of a fuzzy logic controller with linear power controller ensures stability of the block within ±0.2°c. The unit comes along with a carrying case and calibration certificate. Inserts are available to match the diameter of the test sensor and gauges of this dry temperature calibrator.
