Ultra Low Temperature Climatic Test Chamber
-75℃ Environmental Chamber Common Refrigeration system Low
temperature Resistance
Ultra Low temperature Chambers Temperature range down to -75 or
-85°C
Despite its compact size, the SM-712, SM-812 can achieve low
temperatures of -75 or -85°C the lowest range of it's class. On the
high end, 100 or 180°C can be reached, depending on the specific
model.
The main benefit of the ultra low temperature test
chambers over our other benchtop models is the unmatched low
temperature range and the touch-screen programmer with USB.
A viewing window, two shelves, and a cable port are included as
standard features.

- Automatic refrigeration switching for efficient operation
- Viewing window with lamp
- Stainless steel interior
- Two stainless steel shelves
- Standard 50mm (2") diameter cable port
- Specimen power supply control terminal
- Mode program setting function
- Except run fixed value program, our chamber is also capable for
mixed program as you set.
