How to choose the constant temperature and humidity test chamber correctly

How to choose the constant temperature and humidity test chamber correctly

A: The temperature range and humidity range you need to test (when you buy a test box, many people have to be larger than the temperature and humidity required for the test. Reserve a point for later use)
B: What is the weight of the test piece?
C: The size of the studio (standard on the Zui is 3/1 larger than what you experimented with)
D: Whether the controller configuration requires programming instrument or common instrument (you need to ask the instrument's control accuracy and display accuracy)
E: For testing, you can request testing and measurement at a quality inspection agency approved by your country or the country where the manufacturer is located.
F: As far as the price is concerned, you need to determine through communication with the manufacturer.

Temperature and humidity can be controlled in a constant temperature test chamber within the specified temperature range. The constant temperature and humidity test chamber I used is used for the stability test of the drug. The temperature control accuracy is plus or minus 0.5 degrees, and the humidity control is plus or minus 3%. A continuous recorder is especially required. This requirement is the minimum requirement for a constant temperature and humidity test chamber, but in actual tests, few manufacturers meet the standard.
