CALsys -35/200 Autocal

Part Code: CALsys -35/200 Autocal



CALsys -35/200 Autocal is a Highly Stable Stirred Liquid Bath for Calibration RTD / Thermocouple and also for compensation of cold junction.

CALsys -35/200 Autocal offers the temperature range of -35 to 200°C. It has a large tank that is filled with liquid (Water+Methanol/Silicon Oil). The liquid is heated or cooled to the desired temperature, where Methanol+Water are used for Negative Temperature and Silicon Oil is for Heating purpose.
It has better stability & uniformity than dry block bath and as it uses of stirred liquid. This CALsys -35/200 is built using CFC-free refrigerants.

The CALsys -35/200 Autocal is an automatic temperature of the calibration system for thermocouples and RTDs. The system consists of Temperature bath PC software, which together contributes to the whole cycle of the auto-calibration process. The system accepts 4 channels, 4 thermocouples, 4 RTDs.The channel configuration can be done with an LCD display via a touch screen keypad. The thermocouple microvolt & RTD ohm reading for each channel is monitored with CJC compensation. After the calibration process complete the PC software generates a report of actual calibrated values for inputs.
