In different locations within a room, the temperature and humidity conditions vary. II. Calibration method (applicable to pointer-type temperature and humidity gauge series)
1. How to calibrate the humidity meter
①. Cover the humidity meter with a wet towel or wrap it entirely for about 30 minutes
②. The humidity gauge at this time should display a humidity reading of 95% RH
③. If the pointer does not point to 95% RH, use the appropriate screwdriver, open the back or the cover plate, and adjust the screw fixing mechanism until the pointer reaches 95% RH.
2. How to adjust the temperature gauge
Use another precise and accurate thermometer as a reference, and calibrate it using the above method until the correct reading is obtained.
III. Usage Precautions and Maintenance:
1. The temperature and humidity gauge should be placed in a well-ventilated area; avoid installing it on a wall exposed to direct sunlight or near the air outlet of the air conditioner. The correct reading can be displayed after 30 minutes.
2. The temperature and humidity gauge must not be exposed to rain, and shall not be installed in a gas environment that corrodes copper components
3. The comfortable human body temperature and humidity are: 18°C—23°C, 45% RH—65% RH
4. The suitable humidity for crops is: 22℃—32℃ with 60％RH—80％RH
5. Users can compare the temperature and humidity data displayed by this product with the appropriate temperature and humidity conditions for storage of various products provided below, to provide a scientific basis for storage.
