Product Description
Series HM35 Ultra-Precision Digital Absolute Pressure Manometer – 0–29 psia, Model HM3531ALJ100
The Series HM35 ultra-precision digital absolute pressure manometer is built for calibration laboratories, industrial hygiene programs, and engineering teams that demand maximum resolution in low-range absolute pressure measurement. Featuring a 0–29 psia operating range and a ±0.05% full-scale accuracy tier, this instrument excels in vacuum-adjacent testing, environmental control systems, and process verification where even slight deviations matter.
Integrated data logging captures system performance over time, while the high-contrast graphical display reveals trends, peaks, and pressure stability at a glance. Each unit ships with a calibration certificate, enabling the manometer to serve as a secondary reference standard for validating pressure transmitters, regulators, and controlled-environment systems.
