Calibration Method (Applicable to the Series of Needle-type Temperature and Humidity Meters)

1. How to calibrate the humidity meter: ①. Cover the humidity meter with a wet towel or wrap it completely for about 30 minutes. ②. At this time, the humidity meter should display a humidity reading of 95%RH. ③. If the needle does not point to 95%RH, use the appropriate screwdriver to adjust the screw fixed frame on the back or after opening the cover to make the needle point to 95%RH.

3. Usage Precautions and Maintenance:

1. The temperature and humidity clock should be hung in a well-ventilated place, avoid being installed on the wall directly exposed to sunlight, and the air outlet of the air conditioner. After 30 minutes, it can indicate the correct reading. 2. Do not expose the temperature and humidity meter to rain, and do not install it in an environment where corrosive gases attack the copper body. 3. The comfortable temperature and humidity felt by the human body is: 18℃ to 23℃, 45%RH to 65%RH. 4. The suitable humidity for crops is: 22℃ to 32℃, 60%RH to 80%RH. 5. Users can compare the temperature and humidity data displayed by this product with the suitable and storage temperature and humidity data provided below, providing a scientific basis for your storage.
