CALsys 1700L

Part Code: CALsys 1700L



CALsys 1700L calibration source is a highly stable standard furnace for calibrating thermocouples in the laboratory. The temperature of the furnace is set and controlled by a self tuned advanced PID controller with automatic super fine adjustment. The standard insert is a Ceramic Tube, which is 37 mm in diameter and 240 mm long and can hold up to four thermocouples. It has been designed for high temperature range calibration and find application in the glass, electrical power, automotive & material processing industries and laboratories.
