Instructions for use
1. The wet and dry thermometer should be hung in a ventilated place to keep the ribbon and pot of water clean.
2. Pour clean water into the kettle below and immerse the yarn into the kettle before use.
3. The humidity checked by this dry and wet thermometer is calculated in degrees Celsius (℃). If the second meter is at the same temperature, it means that the water for vapor in the air has reached the saturation point.
4. The rotary calculation plate installed at the lower end of the wet and dry thermometer is a dry and humidity comparison table to check the humidity in the air.
5. How to use: According to the rotation calculation of the wet and dry meter thermometer, make the dry bulb temperature scale line up with the wet bulb temperature scale. The reading number indicated by the for arrow direction below is the relative humidity.
Package included:
1 * Dryness meter hygrometer thermometer
