CALsys 650 SP Autocal

Part Code: CALsys 650 SP Autocal



CALsys 650 SP Autocal offers easy to use portable temperature calibrator with a medium temperature range from 50 to 650°C. It is a highly stable standard furnace for calibrating thermocouples I RTD.This calibrator can be used on-site in workshops, test and measurement rooms as well as laboratories. The comparison volume is a metallic block of special material, which has a diameter of 32mm and 140mm long. The CALsys 650 SP Autocal is an automatic temperature calibration system for the Thermocouple and RTDs.
