Product Description
Precision Digital Gage Pressure Manometer – HM3531GMG310
The Series HM35 Precision Digital Gage Pressure Manometer is engineered for ultra-low-pressure measurement and calibration in laboratory, industrial hygiene, and regulated testing environments.
This configuration provides a 0–7.25 PSI measuring range with 0.20% full-scale accuracy, onboard data logging, graphical trend display, and a factory calibration certificate — making it ideal for breathing-air systems, regulator validation, leak testing, and micro-pressure verification.
Designed for air and compatible gases, the HM3531GMG310 supports compliance audits, QA programs, and sensitive pressure diagnostics where repeatability and traceability are mandatory.
