Model 224 Cryogenic Temperature Monitor
Brand: Lake Shore | Category: Nanotechnology
The Model 224 is a cryogenic temperature monitor with 12 sensor channels that measures temperature down to 300 mK. It reads silicon diodes and both positive and negative temperature coefficient resistance sensors, using 4-lead differential measurement with current reversal on RTDs.

- 240 Series Input Modules
The 240 Series Input Modules read cryogenic temperature sensors and pass the measurement onto a distributed control network. They are intended for large scale installations that use PLC based control rather than a single benchtop instrument. They suit systems with many sensor points spread across a facility.
- Model 218 Cryogenic Temperature Monitor
The Model 218 is a cryogenic temperature monitor with eight sensor inputs, arranged in two groups of four. It reads diode and RTD sensors down to 1.2 K and updates at up to 16 readings per second in total. It is used where several points in a cryogenic system must be monitored at once.
- Cryogen-Free Cryogenic Cold Trap Cryostats
These cold traps use a mechanical closed-cycle cooler to adsorb noble gases, including helium, neon, argon, krypton and xenon. The cold surface is held below 9 K so gas is captured from a vacuum line without liquid cryogens. Three models cover different upper temperature limits.
