IEC60068-2-1 Rapid Temperature Change Test Chamber For Testing Of Raw Materials

Product information:

This rapid temperature change test chamber is required by IEC 62196-1: 2022 clause 26.7.2.

It 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 reliability of storage, transportation and use of products under high and low temperature rapid alternating humid heat environment.

Manufactured in accordance with 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 equipment adopts a closed chamber structure with the following features:

1. Energy saving and consumption reduction: The gas-liquid bypass mode is used to adjust the cooling capacity to achieve constant temperature and humidity.

2. Easy to operate: using programmable temperature and humidity controller (7-inch 16-bit true color touch screen), experimental data recording and processing are flexible.

3. High reliability: key components are imported components to ensure longevity and reliability; efficient oil separators ensure compressor life.
