Product Description
Series HM28 Handheld Digital Pressure Manometer – 0–14.5 PSI / 100 kPa, Model HM28D3H10000
The Series HM28 handheld digital manometer is designed for technicians, calibration laboratories, and commissioning teams that require portable high-accuracy pressure measurement across multiple test modes. Covering a 0–14.5 psi (100 kPa) range, this instrument supports differential, gauge, and absolute pressure measurement with selectable accuracy tiers down to ±0.05% full scale.
Its compact handheld form factor makes it ideal for field diagnostics, bench testing, and compliance verification. A calibration certificate is included with every unit, allowing the HM28 to function as a secondary calibration reference for validating regulators, transmitters, and process instrumentation.
