January 05, 2021

GDW- 150

High and low temperature test chamber

Suitable for testing and determining electrical, electronic and other products and materials for high temperatures,

Parameters and performance after temperature changes at low temperatures or constant tests.

Structural features :
1, the original French imports "Taikang" refrigeration unit and a full set of refrigeration accessories. Refrigeration mode adopts single stage

Or two-stage cascade cooling ( air or water ) .
2, the original Japanese imported temperature control instrument ( except constant temperature box ) input mode PT100 sensor.
3. The inner tank is made of high quality imported stainless steel plate, and the outer casing is electrostatically sprayed on A3 steel plate.
4, stainless steel scale high-efficiency electric heater.
