When purchasing high and low temperature test chambers , both inside and outside should be taken into account, both attention to its appearance and its structural properties. Performance quality is the key, picking the right choice when buying, will save a lot of trouble for the future. So what should you pay attention to when selecting high and low temperature test chambers? Baoditong introduces you. Â
1. Mechanical properties and physical properties such as materials exposed to low temperature environments, solders and welds should ensure the normal use of the test chamber.
2. The inner wall should be made of heat-resistant and non-oxidizable materials .
3 , the insulation material should be able to withstand high temperatures and have self-extinguishing properties. The thickness of the insulation layer should be such that the temperature of the externally accessible part of the test chamber is not higher than 50 ° C at high temperature; at low temperature, when the ambient temperature is 30 to 35 ° C and the relative humidity is 75% to 85% , the outer wall of the tank, There should be no obvious condensation on the door and seal.
4, antipyretic and cooling devices may not face the test sample.
5 , the sealing strip of the door should not be easy to age under high temperature and harden at low temperature, should not lose the sealing performance, and should be easy to replace.
6, should an observation window, the illumination device should be equipped with the working chamber.
7 , should have temperature adjustment, indication, recording and other instrumentation devices.
8, the sample rack should be suspended or placed in the sample. The sample holder should maintain a certain mechanical property under high or low temperature conditions and is easy to handle.
9, the cooling piping system should be reliable seal not leak, leaking oil.
10, the power supply should be provided with a test lead is introduced via line working chamber.
11, appearance of the coated layer should be smooth, homogeneous hue, without exposed at the end, from the floor, blistering or scuff marks.
If you have any other questions during the operation of the high and low temperature test chamber, you can consult our technical staff. Sincerely at your service.
