Differential Pressure Manometer 5 psi

The TRIPLETT DPR305 is a digital manometer built for HVAC technicians and maintenance professionals who need to measure gas or air pressure differentials. It covers a range from -5 psi to 5 psi with an accuracy of +/- 0.3 percent of full scale.

Measurement range and resolution

The instrument reads positive and negative pressure up to 5 psi, suitable for checking furnace draft, duct static pressure and filter condition. Beyond that span the display cannot resolve the signal, so higher-pressure hydraulic or industrial lines require a different gauge.

Quick-disconnect interface and power

Process connections use a quick-disconnect fitting for fast hose attachment, and the unit runs on three AAA batteries with an auto power-off function to extend life. The backlit display shows readings in psi only, and no NIST-traceable calibration certificate is included.

Questions about this item

Will the DPR305 manometer work with the quick-disconnect fittings on my existing pressure-washer hose?

The DPR305 uses a quick-disconnect process connection, so it attaches directly to standard pressure-washer quick-disconnect fittings without extra adapters.

How do I confirm the DPR305 is reading accurately after I install the batteries?

The backlit digital display shows pressure in psi with a data-hold function; readings within ±0.3 % of the 5 psi full scale indicate the unit is operating correctly.

Does the DPR305 come with everything needed to start measuring, or must I buy batteries separately?

Three AAA batteries are included in the box, and the unit has auto power-off, so no separate purchase is required before first use.
