Do you know the linear temperature range of the rapid temperature cycle test chamber?

June 9, 2021

Recently, I have received many feedbacks that many problems have been encountered during the damp and heat test in the rapid temperature cycle test chamber. For example, the actual humidity will be too high, even reaching 100%. On the contrary, the value is too low and the target humidity is too large. Do you know what is the linear temperature range of its equipment? Next, the editor will tell you an introduction:

 

The general humidity index of ordinary domestic and foreign rapid temperature cycle test chambers is mostly 20-98%RH or 30-98%RH. If the humid heat test chamber does not have a dehumidification system, the humidity range is 60-98%. The humidity outside this range is too high or Too low is problematic.

 

If the humidity reaches 100%, it may be that the gauze on the wet bulb sensor of the equipment is dry. Then check whether there is water shortage in the wet bulb sensor of the rapid temperature cycle test box. The water level in the sink is automatically controlled by a water level controller. Yes, check whether the water supply system of the water level controller works normally and whether the water level controller works normally. It is also possible that the wet ball gauze will harden due to the long use time or the purity of the water supply, making the gauze unable to absorb water and dry. The above phenomenon can be eliminated by replacing or cleaning the gauze.

 

If the humidity value is too low, it is mainly caused by the humidification system not working. Check the water supply system of the humidification system of the rapid temperature cycle test box, whether there is a certain amount of water in the water supply system, and whether the water level control for controlling the water level of the humidification boiler is normal. Is the water level normal? If everything above is normal, the electrical control system should be checked. This should be done by professional maintenance personnel.

 

The rapid temperature cycle test chamber is a precision instrument, and humidity is very important, so when the value is abnormal, find out the cause and solve it in time, otherwise it will affect the test result; the above is the editor to share with you the linear temperature range of the rapid temperature cycle test chamber All content.
