Product Description
Ultra-Precision Digital Differential Pressure Manometer – HM3531DLJ100
The Series HM35 Ultra-Precision Digital Differential Pressure Manometer is engineered for laboratories, calibration facilities, and industrial hygiene programs requiring the highest available accuracy in low-pressure measurement.
This configuration measures 0–29 PSI differential pressure with 0.05% accuracy, delivering reference-grade performance for airflow diagnostics, filter certification, cleanroom validation, and pressure instrumentation verification.
With integrated data logging, stainless steel wetted components, graphical trend display, and a factory calibration certificate, the HM3531DLJ100 functions as a portable secondary standard in both laboratory and field environments.
