Product Description
Ultra-Precision Digital Differential Pressure Manometer – HM3531DLM110
The Series HM35 Ultra-Precision Digital Differential Pressure Manometer is engineered for laboratories and calibration environments requiring maximum measurement fidelity.
This configuration delivers a 0–245 PSI differential pressure range with 0.05% accuracy, onboard data logging, and graphical trend analysis — supported by a factory calibration certificate for secondary-standard applications.
Designed for air and compatible gases, the HM3531DLM110 excels in HVAC commissioning, filtration validation, regulator testing, and process diagnostics where regulatory confidence and traceable performance matter.
