Importance of changing gauze: The gauze in the constant climate chamber is mainly used to maintain the measurement of wet-bulb humidity, which is calculated by the wet-dry-bulb method. The state of the gauze directly affects the accuracy of humidity measurement. When the gauze turns yellow, hardens, or the water absorption becomes poor, it needs to be replaced, because this will affect the humidity reading, which may cause the humidity to fail to decrease and the displayed value to continue to b...
