Part Code: CALsys 650 M



The Tempsens make metrology grade calsys 650 M is a user friendly, highly accurate easy to use dry block calibrator with the inhanced speed and portability its offers best in class accuracy stability, axial uniformity, radial uniformity, loading and hysteresis. all persmeters featurings the highest available performance and well adopted for characterization and performance validation for contact type temperature sensors like thermocouple RTD temperature guages for a wide temperature ranges. The comparison volume is a metallic block of special material, which has a diameter of 38mm and 180mm long. The CALsys 650 M Upgraded with automatic temperature calibration system for the Thermocouple and RTD's. The system consists of Temperature bath and PC softwa re, which together contribute to the whole cycle of auto calibration process. The system accept 4 channels,4 Thermocouples or 4 RTD's.The connection for these channels through special type of 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 process complete the PC software generates a report of actual calibrated values for the inputs. With the Tempsens make Compact Temperature Calibrator, you have chosen an extremely effective instrument which we hope will live up to all your expectations. This is a fast, timesaving, and reliable true industrial temperature calibrator designed for on-site use.
