75 PSI Manometer ( HTC – PM-6175 )

Description

The HTC PM‑6175 Digital Manometer is a precision-grade handheld instrument designed to measure differential pressure across a wide 0 to ±75 psi (±2078 inH₂O, ±5168 mbar) range. Its expansive measurement span makes it invaluable for professionals in HVAC diagnostics, cleanroom validation, industrial service, and environmental engineering tasks.

Featuring eleven selectable pressure units, including psi, inH₂O, mbar, kPa, inHg, mmHg, oz/in², ftH₂O, cmH₂O, bar, and kg/cm², this manometer adapts seamlessly to diverse regional and technical standards. It provides high resolution—0.01 psi, 1 inH₂O, 1 mbar, 0.1 kPa, 0.01 inHg, and 0.1 in oz/in²—delivering clear and precise readings across all supported units.

Accuracy is a standout strength: ±0.3% of full scale, with linearity within ±0.1% FS and repeatability of ±0.25% FS, ensuring stable and consistent pressure readings even in repeated assessments. Real-time error alerts (“ERR1” for over-range, “ERR2” for under-range) prevent misinterpretation during high-pressure scenarios.

The manometer’s large backlit LCD display enhances visibility in dim mechanical rooms or duct environments. Status icons include measurement units, MAX/MIN/Average logging, data hold, low battery warnings, and error indicators, making it easy for field users to review measurement trends and system behavior instantly.

Functionality extends to features critical for HVAC and cleanroom applications. It supports Data Hold, MAX/MIN/Average recording, unit conversion at a push, and offset or zero calibration, which aid in comparing pressure differentials across zones, filters, or equipment setups.

Pressure ports are fitted with 1/8″ (3.18 mm) quick-connect fittings, compatible with included soft and hard tubing and metal gas mouth adapters—facilitating fast, secure setup across diverse test scenarios. The robust ABS housing measures approximately 140 × 20 × 50 mm and is lightweight (~400 g), offering ergonomic comfort and portability for technicians and engineers working on-site.

Powered by a standard 9 V battery, the device includes Auto Power-Off to conserve energy and features a low-battery indicator so users are never caught off guard in the field. It reliably operates in ambient conditions between 0–40 °C (32–104 °F) and supports non-condensing humidity up to 90%, with safe storage temperatures from –10 °C to +60 °C.

Standard accessories include a soft carrying case, soft/hard tubing set, gas mouth metal adapters, and user manual—allowing immediate deployment and seamless integration into on-site diagnostics and commissioning toolkits.
