CALsys 1200 3Z

Part Code: CALsys 1200 3Z



CALsys 1200 3Z calibration source is a highly stable standard furnace for calibrating thermocouples in the laboratory. The temperature of each zone of the furnace is set and controlled by a self tuned PID controller(master + Slave) with automatic super fine adjustment. The standard insert is a metallic block of special material, which is 37mm in diameter with 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 & laboratories.
