Product Description
Series HM28 Handheld Digital Absolute Pressure Manometer – 0–15.9 psia / 110 kPa, Model HM28A3I10000
Designed for engineers and calibration technicians working with sealed systems, vacuum-adjacent processes, and low-range absolute pressure environments, the HM28A3I10000 delivers precise measurement from 0–15.9 psia (110 kPa absolute) with selectable accuracy grades down to ±0.05% full scale.
Its handheld form factor pairs laboratory-level performance with field mobility, making this model ideal for leak testing, environmental chambers, pneumatic verification, and regulator calibration. Each unit ships with a traceable calibration certificate, enabling secondary-standard use in quality-controlled facilities.
