Under normal circumstances, use absolute pressure gauges to measure
On the cement floor, use this watch
The atmospheric pressure of the environment is approximately equal to 0.1MPa (1 kg per square centimeter, also known as 1 kg pressure).The gauge is to a pressure of 0 to calculate the pressure.Absolute pressure is the absolute pressure measurement. The pressure is measured at 0 under the vacuum. The absolute pressure in the atmospheric environment is 0.1MPa (1 kg per square centimeter). Absolute pressure gauge pressure = +0.1MPa. The use of the situation, according to the needs of the selection, the general situation is the use of absolute pressure table

Absolute pressure gauges are suitable for measuring gas and liquids.Nominal diameter: Phi 70 mm, 110 mm, 160 Phi 250mmAccuracy class: 0.4, 1, 1.6, 2.5Range: 0~16Kpa, 0~2500KpaInstallation: radial, axialProtection level: IP68Case material: 304SS, 316SS, carbon steel, aluminumMeasuring element material: 1, accuracy 0.4, copper alloy, 50CrV2, precision 1.0~2.5 grade copper alloy, 1Cr, 316SS and so onTable cover: safety glassPressure interface: radial or axial G1/2, M20*1.5, or specified special requirementsWorking pressure: the static load is 3/4 times of the upper limit of measurement, and the switching load is 2/3 times of the upper limit of measurement, and the short-time pressure is applied to the upper limit of measurement.Working conditions: ambient and medium temperature should not exceed -40~70 (class 0.4) C or C -50~160 (precision 1.0~2.5); relative humidity is less than 80%Remarks: the screws on the back of the case must not be loosened.
