Product Description
Precision Digital Differential Pressure Manometer – HM3531DLM610
The Series HM35 Precision Digital Differential Pressure Manometer is engineered for high-accuracy pressure comparison and calibration in laboratories, industrial hygiene programs, and regulated test environments.
This configuration delivers a 0–245 PSI differential pressure range with 0.10% of reading accuracy, onboard data logging, graphical trend visualization, and a factory calibration certificate — making it ideal for ventilation system diagnostics, regulator testing, filter monitoring, and process validation.
Designed for air and compatible gases, the HM3531DLM610 supports compliance audits, commissioning work, and secondary-standard calibration programs where traceability and stability are critical.
