Detailed Product Description

IEC 60068-2-78 Intelligent Control System Temperature And Humidity Chamber -40 ℃～+180℃

Product overview:

This test chamber is used for cold, heat, humidity and dryness 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 alternating heat and humidity.

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”

IEC60068-2-78:2012 “Environmental Testing-Part 2-78: Tests-Test Cab: Damp heat, steady state, IDT”

IEC60068-2-30:2005 “Environmental Testing-Part 2-30: Tests-Test Db: Damp heat, cyclic (12h+12h cycle), IDT”

Structure:

This machine adopts a closed chamber structure with the following features:

A. It has an extremely wide temperature and humidity control range to meet the various needs of users.

B. It adopts a unique balanced temperature adjustment and humidity control mode to adjust the ideal temperature and humidity environment. The heating and humidification capability are stable and balanced, and the temperature and humidity control are 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.
