3 Zones Thermal Shock Environmental Testing Chamber
Complied Standards & Clauses
The 3-Zones Thermal Shock Test Chamber meets the standard requirements of IEC 60068-2-1:2007, Environmental Testing—Part 2-1: Tests—Test A: Cold, IDT; IEC 60068-2-2: 1974 Environmental testing for electric and electronic products—Part 2: Test methods—Tests B: Dry heat; IEC 60068-2-14:1984, Basic environmental testing procedures—Part 2: test-test N: Change of temperature, IDT; MIL-STD-883 and etc.
Equipment Overview
The 3 Zones Thermal Shock Test Chamber is composed of three zones of high temperature heat storage zone, low temperature cold storage zone and product test zone. The products to be tested are placed in the test compartment. The unique heat-storage and cold-storage effect of the heat-dissipating structure is adopted, and the effect of alternating high temperature and low temperature shocks can be achieved quickly through the switching of the damper.
It is used to test whether the product is adversely affected by the rapid change of high and low temperature in the way of the object to be tested does not move. It is a necessary test equipment for metal, plastic, rubber, electrical and electronic, auto parts and other material industries.

Questions & Answers
Q: What's the difference of the 3 Zones and 2 Zones thermal shock test chamber?
A: The Two-Zone Thermal Shock Test Chamber, also called Basket-Type Thermal Shock Test Chamber. The test chamber has only two zones, the high temperature zone and low temperature zone, and there is no test zone. Its "test zone" is a hanging basket, loaded with test samples to move between the high temperature zone and the low temperature zone. The conversion time is only 10 seconds, which can better simulate the instantaneous temperature conversion shock.
The Three-Zone Thermal Shock Test Chamber is divided into three parts: high temperature zone, test zone, and low temperature zone. It is very simple to test. Placing the test sample in the middle position, when the temperature is switched, only the corresponding door valve needs to be opened.
