YM3 Empty box pressure gaugeDetailed product description：

1、 Purpose:
The YM3 empty box pressure gauge is mainly used by gas stations, environmental protection, geology and mining, laboratories and other departments to measure atmospheric pressure.

2、 Introduction to Working Principle:
This instrument is equipped with three pressure sensitive element capsules, which produce axial displacement with changes in atmospheric pressure. Through the crank connecting rod mechanism and gear transmission mechanism, it drives the pointer mounted on the pointer shaft to make circular motion on the dial. The value indicated by the pointer on the dial is the atmospheric pressure value at that time.

3、 Main technical indicators:
1. Measurement range 800-1060hPa
2. Temperature range for use (-11~41) ° C
3. The minimum division value of the instrument thermometer is 1 ° C
4. Minimum division value of dial 1 hPa
5. After indication, temperature, and supplementary correction, the measurement error does not exceed ± 2hPa
6. The weight of the instrument shall not exceed 1.5kg
7. Instrument size 156x156x115mm3
