## U **RS232C Serial Interface and Alarm Relays** 

The CYD211 temperature monitor provides the accuracy, resolution, and interface features of a benchtop temperature monitor in an easy to use, compact instrument. With appropriate sensors, the CYD211 measures temperature from 1.4 to 800 K and in difficult sensing conditions, including high vacuum and magnetic fields. Standard features on the CYD211 include alarms, relays, user-configurable analog voltage or current output, and a serial interface. The CYD211 is an ideal choice for liquified gas storage/monitoring, cryopump control, cryo-cooler, materials science applications, and for applications that require greater accuracy than thermocouples allow.
