Where is the sensing probe of the mechanical thermometer and hygrometer?

Mechanical thermo-hygrometer as the name suggests is The thermometer and hygrometer made based on mechanical principles can complete the instructions without using energy such as batteries, and is safe and pollution-free. Mechanical thermometers and hygrometers usually have two pointers, one pointing to temperature and one pointing to humidity. Generally, the larger reading disk is temperature and the smaller reading disk is humidity, but the reverse is also true. So how do we identify it? Just look at the units. The temperature unit is °C, the humidity unit is %RH, and the humidity range is above 0.

Such thermohygrometers are mainly used in places that have certain requirements for temperature and humidity, such as warehouses, computer rooms, data rooms, etc.

At this time, someone may ask: Where is the sensing probe of the mechanical temperature and humidity meter?

The induction probe is located on the back of the meter and can be in good contact with the air. The hanging position cannot be in direct sunlight or at an air-conditioning vent. Please wait 30 minutes for reading after hanging for the first time.
