CALsys-80_50 Autocal

Part Code: CALsys-80_50 Autocal



CALsys -80/50 Autocal is a automatic calibration system for  RTD / Thermocouple and also for compensation of cold junction. CALsys -80/50 offers the temperature range of -80 to 50°C. It has large tank which is filled with liquid Methanol. The liquid is heated or cooled to the desired temperature. It has better stability & uniformity than dry block bath and as it uses of stirred liquid.The system consist of Temperature bath and PC Software, which together contribute to the whole cycle of auto calibration process.The system accepts 4 channels, 4 thermocouples or RTDs. The connection for these channels through special type off locking connectors. The channel configuration can be done with LCD display via touch screen keypad. The thermocouple microvolt & RTD ohm reading for each channel is monitored with CJC compensation. After the calibration PC software generates a report of actual calibrated values for the inputs.
