Product Model: YB-150B Theme Features: This type of precision pressure gauge is equipped with a zero adjustment precision gauge, which can be zeroed by oneself before testing or use. Mainly used for verifying industrial ordinary pressure gauges, it can also accurately measure the pressure of non corrosive, non crystalline, and non solidifying media on copper alloys and alloy structured copper materials at the process site. The instrument is equipped with a mirror ring below the scale line, which provides clearer and more accurate readings during use. The pressure measuring elastic element has undergone special processing to ensure stable and reliable performance. After matching and debugging with high-precision transmission mechanisms, it can ensure accurate indication accuracy. Production enterprise: Hongqi Instrument Co., Ltd
