CALsys 300SP

Part Code: CALsys 300SP



CALsys 300SP calibration bath is a highly stable standard stirred liquid bath for calibrating RTDs/Thermocouples and other temperature sensors in the laboratory. The temperature of the bath is set and controlled by a self tuned PID controller with automatic super fine adjustment.

The unique features is portability with very high stability and uniformity. The medium used in the bath is silicon oil.
