Due to global supply disruptions, longer than usual lead times may be experienced.

The Lake Shore Model 224 temperature monitor offers precision measurement in a wide range of cryogenic and higher-temperature applications with the ability to monitor up to 12 sensor channels easily. Used with Lake Shore Cernox® sensors, the Model 224 enables reliable and repeatable temperature measurement over a broad range and as low as 300 mK.

Cernox thin-film RTD sensors offer high sensitivity and low magnetic field-induced errors at cryogenic temperatures. In addition to Cernox, the Model 224 supports other NTC RTDs, PTC RTDs such as platinum sensors, and diodes such as the Lake Shore DT-670 Series.

You can set up different sensor types and responses on each input to support simultaneous measurement of various critical points in a system. Examples include monitoring multiple cryogenic refrigeration systems (e.g., liquid nitrogen Dewars, He-4 cryostats, and closed-cycle refrigerators), multiple stages within systems operating at different temperature levels, thermal gradient profiling, redundant measurements of critical values, leak detection, and other cryogenic applications where you need accurate readings at multiple points.
