Temperature Test Chambers

Temperature test chambers focus on the required temperature simulation test from 4 optional low temperature -70 °C; -60°C; -40°C; -20°C to high temperature 180 °C.

1.Chamber working room size could customize.
2.If test specimens have active load during test, please inform us.
3.This is temperature only model, if need make humidity test, please refer to humidity chambers.

Temperature test chambers focus on the required temperature simulation test from 4 optional low temperature -70 °C; -60°C; -40°C; -20°C to high temperature 180 °C. 

Chambers with Single-stage Refrigeration systems are capable of achieving workspace temperatures down to -20°C. This is fine for many commercial and industrial tests that require low temperatures of typically 0°C, -10°C or -20°C. A single-stage system uses one compressor to directly cool the workspace.

Chambers with Cascade Refrigeration systems are capable of achieving workspace temperatures down to -40°C~-70°C depending on model. This is required for many ruggedized industrial, automotive and military test procedures that require low temperatures of typically -40°C, -55°C or -65°C. A cascade system uses two interdependent compressors.
