Digital micro pressure gauge is a kind of high stability of pressure gauge, is suitable for gas, liquid of positive pressure, negative pressure and differential pressure measurement, is the environmental monitoring station, laboratory, medicine and health care, building air conditioning heating, ventilation, clean room pressure of the ideal instrument, test or calibration with epithelial hosting measuring gas flow rate. Digital micro pressure gauge characteristics 1. Portable, LCD display, digital direct reading, digital reset. 2. The United States honeywell micro pressure sensor, high resolution, high accuracy, high stability. 3. Select and numerical stability. Can be used under suitable for all kinds of working state. 4. The battery of continuous use of up to 100 hours, embedded for external power supply. 5. Measurement data within the designated storage and machine temperature display function. Digital micromanometer note 1. Instrument essence should be far away from the vibration source, strong electromagnetic fields. The environment temperature must be stable. 2. In general, not measuring the corrosive gas and liquid pressure. 3. Pressure shall not exceed the permitted scope of overload. < 500 pa instruments should be used under the condition of constant temperature. 4. Instrument display bALo, said a battery should be replaced. 5. Instruments should be inspected cycle ( The tentative one year) 。
