CALsys 1200L-S

Part Code: CALsys 1200L-S



CALsys 1200L-S 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 PID controller with automatic super fine adjustment. The standard insert is a metallic block of special material, which is 37mm in diameter with 380 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. Special Version with 3 zone furnaces is available.
