Constant temperature and humidity test chamber temperature is not stable?

When everyone is some application of laboratory equipment for the test, sometimes encounter some problems. In the constant temperature and humidity test chamber temperature instability is a common problem, met a people first to analyzing a what conditions will appear this kind of problem. 1, first check the refrigeration compressor is in operation in the whole process can be started, if the operation can be started, means that from the main switch power supply to the constant temperature and humidity test chamber compressor electric line are all normal, no problems at that time can remove electrical system. It's no problem for me to check the electrical system, the refrigeration system to check again. 2, check the a2 group refrigeration compressor unit, if the ultra-low temperature ( R23) Stage compressor exhaust pipe and the suction pressure of a standard is a bit low, and inspiratory pressure in time, this suggests that the amount of refrigerant refrigeration unit is not significantly. Unit 3, use hand to touch the main R23 compressor exhaust and suction pipes, such as found that the temperature of the exhaust pipe is not high, the temperature of the suction pipe is not low, Not frosting) , it suggests that the lack of the main unit R23 refrigerant. 4, a leading unit and another for auxiliary units, high cooling speed, unit 2 groups also work at the early stage of the temperature to maintain link, 2 groups still another work unit. For basic stable temperature, stop work auxiliary units, by the main unit to keep the temperature cool and smooth. 5, if the main unit R23 leakage, can make the cooling effect of the main unit is not large, because the cooling process, the two units in other work, so without temperature stable condition, and reduce the cooling speed. 6, in the temperature maintaining link, once the auxiliary units to stop working, the main unit and no cooling effect, constant temperature and humidity test the gas temperature in the cabinet will be slow to rise, when the temperature rises to a certain level, the automatic control system will start again auxiliary unit to cool, then auxiliary units and stop working, and so constantly, then there will be a low temperature to maintain the common fault condition. The interpretation of the above is the cause of the constant temperature and humidity test chamber temperature instability, hope can help you, if you want to learn more about information of constant temperature and humidity test chamber, welcome to the online consulting service or call the company service hotline ( Website top right corner) For consultation, we will wholeheartedly provide high quality service for you!

What Are the ISTA Standard Tests and ISTA Testing Equipment?
ISTA (International Safe Transit Association) standard tests are globally recognized transportation packaging test procedures designed to evaluate the safety and reliability of products and their packaging throughout the logistics chain. By simulating real-world transportation conditions such as drops, vibration, impact, stacking, and compression, ISTA testing helps identify potential packaging weaknesses before products enter large-scale distribution. ISTA testing equipment—including drop testers, vibration testers, incline impact machines, and compression testers—plays a critical role in accurately reproducing these conditions under laboratory settings. Proper selection and use of ISTA-compliant equipment enable manufacturers to reduce transportation damage, lower return costs, enhance packaging design, and improve customer confidence in product quality and logistics safety.
Why Is Shoe Slip Resistance Tester Important for Footwear Safety?
Slip resistance is one of the most critical performance indicators for modern footwear, especially safety shoes used in industrial and high-risk working environments.
