Lake Shore benchtop cryogenic instruments are trusted throughout the world for precision temperature measurement—now that same measurement performance can be achieved in widely distributed high energy applications like particle accelerators and fusion reactors as well as other large industrial sites.

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.

The Model 218 is our most versatile temperature monitor. With eight sensor inputs, it can be used with nearly any diode or resistive temperature sensor. It displays all eight channels continuously in K, °C, V, or Ω. The measurement input was designed for the demands of cryogenic temperature measurement; however, the monitor’s low noise, high resolution, and wide operating range make it ideal for non-cryogenic applications as well.

Lake Shore offers a variety of temperature sensors in packages that enable mounting in very tight areas. But for some applications (especially if the sensors have to be immersed in liquid) you need to do more to protect the sensor circuitry. For these applications, a cryogenic temperature probe is the optimum choice. Encased in one of these stainless steel thermowell fixtures, the sensor can perform as designed, unaffected by high pressure, and sealed to keep electrical components and wiring protected from fluids and other elements.

The HR Series is a new line of high reliability cryogenic temperature sensors for mission-critical applications. Starting with our proven temperature sensor technology, we have developed a family of off-the-shelf sensors that have already undergone extreme testing steps to assure you of extra reliability.

Thermocouple wire is used in a variety of cryogenic applications, but special techniques must be employed to approach temperature accuracies of 1% of temperature, even without consideration for the effects of high magnetic fields or high radiation fluxes. The problems are further complicated by exposure to variable gradient conditions at cryogenic temperatures.

CS capacitance sensors are ideally suited for use as cryogenic temperature control sensors in strong magnetic fields because they exhibit virtually no magnetic field dependence. Displacement current is not affected by magnetic fields. Consequently, temperature control fluctuations are kept to a minimum when sweeping magnetic field or when changing field values under constant temperature operation.
