Dongguan Hongjun Instrument & Equipment Co., Ltd. reminds customers on how to maintain high and low temperature alternating humidity and heat test chambers, which can be categorized into single-point high and low temperature cycle test chambers and programmable high and low temperature cycle test chambers. They are both used for testing the structure or composite materials of a material, and can measure the extent to which the material can withstand extreme temperatures. This helps to avoid physical damage or chemical changes caused by thermal expansion and contraction during testing. It is inevitable that some damage will occur to the equipment during testing, and in such cases, regular maintenance by the manufacturer is essential to reduce the rate of damage to the test chambers.

Hongjun Brand Manufacturer's Maintenance Points:

One, ensure that the drainage pipes are properly connected. Check if the protective switch (dry bulb overtemperature) is set to a very high temperature, with its high temperature range being 40℃ to 50℃, and the overtemperature protection temperature setting point being 50℃ to 60℃.

Ensure the humidifier's water tray is at the correct level, and check the water level indicator on the control box after a few minutes of water supply.

Three, confirmation of whether the wet bulb over-temperature protection switch is set at 95℃. After the test cloth operates at a high temperature above 85℃ during testing, it should be replaced before the next operation, otherwise, it will no longer absorb moisture. It is important to note that when replacing the test cloth, please wash your hands first to avoid losing the functionality of the test cloth. The packaging of the test cloth should also be sterilized.

After confirming the above, lower and secure the fixed foot properly.

Here is the maintenance method for the low-temperature alternating humidity test machine. To extend the lifespan of the equipment, we hope you will treat it kindly and ensure proper maintenance. After each test, please check that both the equipment's power supply and the main power are turned off. Hongjun manufacturer can customize according to customer specifications and dimensions!
