IEC 60068-2-1 -40℃- 250℃ Range Adjustable Temperature And Humidity Test Chamber 240L
Product overview:
This test chamber is used for cold, heat testing of raw materials and devices such as electronics, electricians, electrical appliances, plastics, etc. The purpose is to confirm the products reliability of storage and transportation under high and low temperature environment.
It conforms to standards:
IEC60068-2-1:2007 “Environmental Testing-Part 2-1: Tests-Test A: Cold, IDT”
IEC60068-2-2:2007 “Environmental Testing-Part 2-1: Tests- Test B-Dry heat, IDT”
Structure:
This machine adopts a closed chamber structure with the following features:
A. It has an extremely wide temperature control range to meet the various needs of users.
B. It adopts a unique balanced temperature adjustment to adjust the ideal temperature environment. The heating capability is stable and balanced, and the temperature control is high-precision and high-stability.
C. Automatic selection of refrigeration circuit: The automatic control device has the ability of automatically starting the running refrigeration circuit according to the set value of temperature, can start the cooling directly under the high temperature state.
The refrigeration adopts the air-cooled condensing unit with fully enclosed compressor (imported).
D. The door is equipped with an observation window, which is convenient for observing the test state of the test sample.
