Model TM-620 Temperature Monitor

The Cryomagnetics Model TM-620 line of temperature monitors provide an easy to configure and use platform for precision temperature monitoring using a wide variety of commercially available sensor designs.

Available in two channel (TM-620-2) and four channel (TM-620-4) configurations.

Cryomagnetics’ Model TM-620-2 (2-Channel) and TM-620-4 (4-Channel) Temperature Monitors are designed to provide the user with easy to use, precision temperature monitoring at a reasonable cost.  

The unit has been designed to meet the requirements of  monitoring temperature in superconducting magnet systems and other cryogenic applications.

The bright TFT-LCD display offers user selectable formats which include simultaneous display of all channels.  A full numeric keypad allows for navigation through an intuitive menus tree where most features and functions can be configured.
