绝压就是绝对压力（工程学称谓，物理学称谓是绝对压强)绝压，指绝对压力：介质(液体、气体或蒸汽)所处空间的所有压力。
备注：绝压表壳背面的螺丝严禁松动。
Remark: Screws at the back of the gauge's case should never be loosened.
气象及实验室等领域进行表压或绝压得测量，也可测负压，真空度等。
Meteorological and laboratory areas, such as gauge or weight measurement must also test negative pressure, vacuum and so on.
绝压 压力表的 压力测量与大气压的波动无关，适合测量气体和 液体。
There is no connection between the pressure measurement of the absolute pressure gauge and the fluctuation of the atmospheric pressure. Therefore, the gauge is suitable for measuring gas and liquid.
