Pressure Manometer

Model HD350

HD350-en-GB_V3.2 7/15

Introduction

Congratulations on your purchase of the Extech HD350. This handheld meter measures and

displays air velocity (speed), air flow (volume), ambient air temperature, and gauge/differential

pressure. This meter is shipped fully tested and calibrated and, with proper use, will provide years

of reliable service.

Features

 Pitot tube Anemometer measurements for Air Velocity and Air Flow (volume).

 Manometer (Differential Pressure) Measurements.

 Simultaneous display of Air Flow or Air Velocity, Temperature, and Pressure.

 5 selectable pressure units of measure.

 Record up to ninety-nine (99) readings (in meter’s internal memory) for each of the three

measurement types (Air Velocity, Air Flow, and Pressure) for a total of 297 readings.

 USB port for connection to a Personal Computer (PC) for real time datalogging of up to 5500

readings stored on the PC.

 Large backlit LCD display.

 Data Hold and Maximum, Minimum, Average memory (MIN/MAX/AVG).

 Auto Power OFF (can be disengaged).
