M173 Temperature Chamber

Pictures may show optional items
Click on the picture for details


Model M173 is a mechanically refrigerated or Cryogenic dual access (front and back) chamber. A hinged lift off front door and pull off machineable thin rear fixturing panel are standard. This makes the M173 ideal for testing or conditioning items that need to be mounted.  An optional hinged lift off door is available for the back and is recommended for long soaks at extreme temperatures.

Model C controller is standard with the M173  
Model C4 programmable controller is optional

§  Cooling Rate

Cryogenic rates are highly dependent upon coolant type
(L–N2 or L–C02), pressure, and quality.  For more information download or request a copy of our brochure on Cryogenic Cooling

Mechanical refrigeration (not available on all chambers) rates are dependant on refrigeration system chosen and other factors.
Note: Cryogenic boost can be added to mechanically refrigerated systems to speed transition temperatures

    Heating Rate

Temperatures shown are for typical heaters. 
Faster and slower rates available.
