Today, Shenzhen Ruitaier Technology will provide a detailed introduction to the external structure and some basic parameters of the constant temperature and humidity test chamber available on the market

Overall design structure of constant temperature and humidity test chamber:
1. It is processed and formed using CNC machine tools, with a beautiful and elegant appearance, and adopts a non reactive handle for easy operation.
2. The inner liner of the box is made of imported stainless steel plate, and the outer liner of the box is made of A3 steel plate spray painted, which increases the appearance texture and cleanliness.
3. The compressor is separated from the casing to avoid interference from the vibration of the constant temperature system on the balance.
4. There is a shock-absorbing platform inside the box, and there is a PVC anti-static board on the shock-absorbing platform
5. The door of the constant temperature and humidity system box is a full frame transparent window with two operation entrances. Latex long gloves are used for isolation to avoid the influence of manual operation on the constant temperature and humidity conditions.
Automated control system for constant temperature and humidity test chamber:
1. The temperature control adopts a touch screen for direct display, sets the required temperature and humidity, and can read relevant data.
2. The refrigeration unit adopts the original French "Taikang" fully enclosed compressor.
Protection system:
Overall equipment overheating; Overall equipment under phase/reverse phase; Overall equipment overload; Refrigeration unit overpressure; Overall equipment timing;
Other protections include leakage, operation indication, automatic shutdown after fault alarm, etc.

Strict quality standards for constant temperature and humidity test chambers:
GB2423.1-2001 Test A "Low Temperature Test Method"; GB2423.2-2001 Test B "High Temperature Test Method";
GB2423.3-93 Test Ca "Constant Damp Heat Test Method" GBT1740-2007 Determination of Moisture Resistance of Paint Films
Meet the standards HJ618-2011, HJ656-2013, and HJ836-2017 of the Ministry of Environmental Protection for the determination of low concentration particulate matter in fixed source exhaust gas by weight method; According to the regulations, a high-precision balance should be placed inside a constant temperature and humidity chamber, and the weighed sample should be weighed after being equilibrated for 24 hours. The constant temperature and humidity adjustment ensures the accuracy of the sample weighing results and the stability and accuracy of the sample weighing data. Non standard products can also be manufactured according to customer requirements.
