Product Introduction

This compact digital manometer combines a temperature-compensated pressure sensor with two top hose connections and a bright display. It is intended for quick differential and static pressure checks where portability matters. Selectable units, zero adjustment and a magnetic rear surface support hands-free measurements at air handlers, filters and duct test points.

Key Features

Temperature-compensated sensor supports repeatable low-pressure readings.

Two protected hose nipples enable differential pressure connections.

Pocket-size housing fits routine inspection and maintenance kits.

Backlit display remains readable in service voids and plant rooms.

Magnetic rear surface enables hands-free mounting on steel equipment.

Optional Pitot tube extends use to duct velocity measurement.

Customer Product Concerns

Routine filter and duct checks require a compact instrument that can be secured near the test taps and read clearly in restricted service locations.

A service instrument must be portable without sacrificing pressure resolution.The compact compensated sensor package provides useful low-pressure resolution in a pocket-size body.

Operators need both hands to position tubing at equipment taps.A magnetic rear surface holds the meter on a steel panel during the reading.

Dim ceiling and plant spaces make small displays difficult to read.An illuminated high-contrast display improves visibility at the test point.

Different procedures specify different pressure units.Selectable engineering units remove the need for manual conversion.

Typical Applications

Cleanroom filter pressure-drop checksHVAC static-pressure measurementAir-handler commissioningDuct Pitot-tube velocity testingRoutine ventilation maintenance
