Q2: Humidity is not displayed or the error is too large
A2: The hygrometer in the early test chamber was a hygroscopic bulb hygrometer, as shown in the following figure or similar figure. It is necessary to cover the wet bulb gauze belt on the wet bulb sensor. The gauze belt must be covered at the root of the sensor, and the tail of the gauze belt must be placed in the wet bulb water box under the sensor. If the water absorption of the gauze tape decreases after long-term use, the humidity display will be abnormal.
