Method for stabilizing temperature constant temperature and humidity test chamber

Method for temperature stable in constant temperature and humidity test chamber

constant temperature and humidity test chamber Total temperature tolerance Or 3K [ Taking into account the measured error, the slow change of the temperature and the temperature change in the working space, but in order to maintain the relative humidity in the specified tolerance range, The temperature difference between any two points in the working space must remain in a smaller range, if the temperature difference exceeds 1K [ , the humidity condition does not reach the requirements, in order to maintain the specified humidity, the short-term fluctuation should be maintained in [ , the temperature of the test sample should be stable in ° C 3K , the following method is stable: 1 , before putting the test sample into the constant temperature and constant wetting box, first place the test box sample in another box After the test sample is placed in a constant temperature and humidity tank, the tank is warmed to ° C
3K , and maintained until the test sample reaches temperature stable
These two methodsNo matter which type is used, the temperature stable time is achieved, and the relative humidity must be in the standard atmospheric conditions for the specified trial, the sample is Constant temperature and humidity test chamber After stabilization, the relative humidity in the box should be raised to not less than 95% , ambient temperature test is ° C 3K Beijing QINSUNRing Test Technical Ministry
