CALsys 650 PLUS 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 / 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 150mm long. The CALsys 650 PLUS is an automatic temperature calibration system for the Thermocouple and RTD's. The system consists of a Temperature bath and PC software, which together contribute to the whole cycle of the auto-calibration process. The system accepts 4 channels, 4 Thermocouples, or 4 RTDs. The connection for these channels through a special type of locking connectors. The channel configuration can be done with 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 the inputs. Our newly designed CALsys 650 PLUS model offers better esthetic design and performance-wise upgraded to the next level. This model offers better cooling time which is 2 times faster than our old model and has stability 30% better than the old CALsys 650 PLUS model. Hence our new model not only saves an important time for our valuable customer but also provides better performance.
