WB—1型数字式两用气压计是在 XW—Ⅱ型微气压差计的基础上研制的。这种仪器可借人工调零的方法以毫巴为单位显示某瞬间的大气压力值(参考气压值)。当大气压力发生变化时,仪器自动地以毫米水柱为单位显示出此大气压力相对于参考气压值的变化量(气压差)。可用于测量并巷通风压力差,也可供气象站,实验室或野外监测大气压力的微小变化。
WB-1 digital dual-use digital pressure gauge is developed on the basis of the XW-Ⅱ micro-pressure differential meter. This instrument can be manually zero adjustment method in millibar units of atmospheric pressure moment (reference pressure value). When the atmospheric pressure changes, the instrument automatically displays the variation (barometric pressure) of this barometric pressure relative to the reference barometric pressure in millimeters of water. It can be used to measure the difference between the pressure of the ventilation system and the ventilation system. It can also be used by the weather station, laboratory or field to monitor small changes of atmospheric pressure.
