Pre – use Inspection of Constant Temperature and Humidity Test Chambers

Source:LINPIN Time:2025-03-17 Category:Industry News

Before putting constant temperature and humidity test chambers into service, some inspection work is essential. Here are the key points to note:
As these chambers are electrically powered, inspect the grounding of the power cord and the functionality of the power supply and electrical protection systems. Also, check the water tank’s water level, ensuring there’s sufficient water for the test. If not, refill according to the testing requirements to prevent water shortage during the test, which could compromise the test results.
Examine the exterior for any leakage on the floor. If leakage is found, do not start the test until the issue is resolved. Also, check the stability of the test chamber, specifically the tightness of the leveling feet. If looseness is detected, secure them before operation to prevent device movement during testing.
By conducting these inspections before operation, potential problems can be identified and addressed promptly, ensuring the smooth commissioning of the constant temperature and humidity test chamber.
Currently, these chambers are widely used in various industries. Shanghai Linpin Instrument Co., Ltd. (a test chamber manufacturer) has provided high – quality test chamber equipment for over 10,000 customers. Linpin’s test chambers can rapidly test items under simulated environments, known for their high precision and stability, earning recognition and praise from numerous clients. In addition to offering top – notch equipment, Linpin also provides technical support services.

News Recommendation
If a constant temperature and humidity test chamber malfunctions due to improper operation or lack of maintenance, it will not only affect the progress of work but also incur costs much higher than those of regular maintenance.
I wonder if anyone has encountered the phenomenon where the equipment trips or trips the circuit breaker as soon as it is started during the use of a high-low temperature and humidity test chamber. Why does this happen?
Thermal shock test chambers, renowned for their outstanding stability and reliability, are extensively employed in the testing of automation components, telecommunications equipment, plastics, aerospace hardware, chemical materials, LEDs, and electronic devices.
In the aerospace, automotive, home-appliance and materials-science sectors, products must routinely undergo prolonged and repeatable exposure within the −80 °C to 0 °C range to verify functional integrity and service life under extreme cold. Nature cannot supply a continuous, controllable and stable sub-zero environment; consequently, low-temperature test chambers are employed to create an artificial cryogenic duty.
Thermal-Shock Chambers (TSCs) impose severe temperature ramps (−70 °C ↔ +200 °C within ≤5 min). Superimposed mechanical and thermal stresses exponentially raise failure rates.
