The high and low temperature alternating test chamber is used to simulate the heat resistance, moisture resistance, cold resistance, dry resistance, and quality management engineering of products under a combination of climate and humidity conditions (high and low temperature operation, storage, temperature cycling, high temperature and high humidity, low temperature and low humidity, condensation testing, etc.). It is applied in the national defense industry, aerospace industry, automation components, automotive components, electronic and electrical components, instrumentation, materials, plastics, chemical, food, pharmaceutical industries, and related products to evaluate the adaptability and characteristics of the tested products under given environmental conditions.
Maintenance methods for high and low temperature alternating test chambers:
1. Before use, please confirm if there is sufficient water stored in the water supply tank of the test chamber; Is the water tank cover properly covered; Reset status of drainage switch.
2. Determine whether a humidity test should be conducted during testing. If only a temperature test is conducted, the test cloth needs to be removed because it cannot absorb water again after running at high temperatures above 85 ℃.
3. Please check that the dry bulb over temperature protection switch of the high and low temperature alternating test chamber should be set to high temperature plus (20 ℃~30 ℃), and the temperature setting point of the over temperature protector should be the temperature setting point (20 ℃~30 ℃).
4. Please confirm if the wet bulb test cloth is clean and moist. Generally, the wet bulb should be cleaned once a month and replaced with a new test cloth every three months.
