Features: 1. The digital pressure gauge is mainly composed of a stainless steel casing, a pressure sensor, and a signal processing circuit. 2. High quality pressure sensor core with high precision, corrosion resistance, impact resistance, vibration resistance, small temperature drift and good stability. 3. Use a low-power processor, 2 AA batteries or a high-capacity high-performance lithium battery without external power. 4. Digital pressure gauge according to the pressure characteristics can be divided into: gauge pressure, differential pressure and absolute pressure three. Digital pressure gauge according to the pressure range can be divided into: micro pressure, low pressure, high pressure. Digital pressure gauge according to the temperature can be divided into: room temperature, medium temperature, high temperature. 5. It is mainly used for precision measurement of petroleum, chemical, aerospace and various industrial gas liquids.
