Product Description
Series HM35 Digital Absolute Pressure Manometer – 0–15.9 psia, Model HM3531ALI200
The Series HM35 digital absolute pressure manometer is engineered for calibration laboratories, environmental-control systems, and industrial verification programs that demand tight control in ultra-low absolute-pressure ranges. With a 0–15.9 psia operating span and a ±0.10% full-scale accuracy tier, this instrument is ideal for vacuum-adjacent testing, chamber validation, and process qualification where pressure stability is critical.
Integrated data logging captures long-term system behavior, while the graphical LCD reveals pressure trends, peaks, and transient events in real time. Each unit ships with a calibration certificate, supporting use as a secondary reference standard for validating pressure transmitters, regulators, and controlled-environment instrumentation.
