Product Description
Series HM35 Digital Absolute Pressure Manometer – 0–15.9 psia, Model HM3531ALI300
The Series HM35 digital absolute pressure manometer is designed for calibration laboratories, industrial hygiene programs, and engineering teams that need reliable ultra-low absolute pressure measurement with traceable documentation. With a 0–15.9 psia operating range and a ±0.20% full-scale accuracy tier, this model is ideal for vacuum-adjacent systems, environmental chambers, and process validation where small changes in absolute pressure are critical.
Integrated data logging records system performance over time, while the graphical display highlights pressure stability, peaks, and transient events. Each unit ships with a calibration certificate, supporting its use as a secondary reference standard for verifying transmitters, regulators, and pressure-controlled systems.
