CPD2/20Mining Precision Pressure Meter (Mining Precision Pressure Meter)

Mining portable air pressure gauge is a portable digital atmospheric pressure gauge instrument designed specifically for ventilation measurement under coal mines and "medium pressure prevention, fire extinguishing technology" needs. It can be used in dangerous places with methane mixtures and coal dust explosion. The instrument can measure the air pressure in the site (resolution is 1Pa), or the relative air pressure difference in each site (resolution is 1Pa), and can also measure the atmospheric temperature, eliminating the air pressure drift caused by atmospheric temperature changes.
