The pressure gauge is divided into a vacuum gauge, a pressure vacuum gauge, a micro pressure gauge, a low pressure gauge, a medium pressure gauge, and a high pressure gauge according to its measurement range. Vacuum gauge is used to measure pressure value less than atmospheric pressure; pressure vacuum gauge is used to measure pressure value less than and greater than atmospheric pressure; micro pressure gauge is used to measure pressure value less than 60000 Pa; low pressure gauge is used to measure 0~6MPa pressure value The medium pressure meter is used to measure the pressure of 10~60MPa; the high pressure meter is used to measure the pressure value above 100MPa.

Pressure gauge according to its display points: pointer pressure gauges, digital pressure gauges, shock-proof pressure gauge housing made of fully sealed structure, and filled with damping oil in the housing (now filled with silicone oil), due to its damping effect can be used at work Ambient vibration or pressure (load) pulsation measurement site. Pressure gauges with electrical contact control switches enable signaling alarms or control functions.

The pressure gauge can be divided into precision pressure gauges and general pressure gauges according to its measurement accuracy. The accuracy of the precision pressure gauges is 0.1, 0.16, 0.25, 0.4, and 0.05, respectively. The accuracy of the general pressure gauges is 1.0, 1.6, 2.5, and 4.0 respectively.
The pressure gauge is divided into a general pressure gauge, an absolute pressure gauge, and a differential pressure gauge according to the pressure reference standard. The general pressure gauge is based on the atmospheric pressure; the absolute pressure gauge is based on the absolute pressure zero; the differential pressure gauge measures the difference between the two measured pressures.
