Optional temperature and humidity chamber needs to pay attention to what the problem?
What type, what test equipment configuration is the most suitable for their own it? Lee Billiton Here, on temperature and humidity chamber for some to buy the voice of experience, I hope you can help manufacturers, research institutes, universities in the purchase of the product, there is a reference index.
First, choose a suitable test equipment, according to the test sample size, selection of the chamber liner. The time trial products (components, assemblies, parts or whole) into climate environmental chamber test, were tested in order to ensure that products can meet the test specifications specified environmental conditions, climate chamber test workspace dimensions are outside dimensions of the product to be followed between three points: 1, the volume of products to be tested shall not exceed the effective working space of the chamber (20-35), for heating products in the test is recommended to use no more than 30mm; 2, the product being tested off the area of ??the wind and on the ratio of the total cross-sectional area of ??the chamber is not greater than the working chamber (35-50); 3, the test product profile from the chamber wall surface should be kept a minimum distance of 100-150mm.
In product performance, we also need to choose carefully! Focus on the following aspects need to be considered!
1, temperature range: The temperature range is much equipment. There are four standard temperature range for customers to choose, A: 0 ℃ ~ 100 ℃; B: -20 ℃ ~ 150 ℃; C: -40 ℃ ~ 150 ℃; D: -60 ℃ ~ 150 ℃. As customer demand for non-standard temperature, it can also produce production, most low temperature to -90 ℃.
2, circulatory function: whether the device has a temperature of circulation, namely: repeated cycles between temperature switching curve cycle. Equipment called high and low so we will circulatory function containing alternating chamber (GDJW). Specific difference between the two, you can click into the "high and low temperature and high temperature test chamber is a concept you?" The technical literature.
3, relative humidity range: whether the device with humidity function. With a relative humidity range of what we call high and low temperature heat chamber (GDS) or temperature and humidity chamber (HS). Humidity range is generally controlled at 20% ~ 98% RH (temperature at 25 ℃ ~ 80 ℃ when).
4, the system controls the selection of hardware. In terms of the hardware purchase, customers are mainly based on the actual operation, the test uses of the product and the combination of cost up options.
