This type of precision pressure gauge is mainly used for calibrating general industrial pressure gauges. It can also be used for accurate on-site measurement of the pressure of non-crystallizing, non-solidifying media that are non-corrosive to copper alloys, alloy structural copper, and other compatible materials. The gauge features a mirror ring beneath the scale markings, allowing clearer and more accurate readings. Its elastic pressure-sensing element undergoes special processing to ensure stable and reliable performance. Combined with a high-precision transmission mechanism and careful calibration, it ensures accurate pressure indication.
