Dwyer 477B Digital Manometer for Air Pressure Measurement

Dwyer 477B Series Handheld Digital Manometer Precise Air Pressure Measurement

Product Introduction

The Dwyer 477B Series Handheld Digital Manometer is a high - precision instrument for air pressure measurement, which is suitable for applications such as laboratory calibration and air - flow measurement in commercial buildings. The following is a detailed introduction:

Features

High - precision Measurement: It can measure positive pressure, negative pressure or differential pressure, with a full - scale accuracy of ±0.10% in the temperature range of 60 to 78°F (15.6 to 25.6°C), which is four times more accurate than most standard manometers.

Multiple Pressure Units: It supports up to seven common English and metric pressure units, and users can select them according to their needs without the need for unit conversion.

Data Storage Function: The manometer has a memory function that can store up to 40 readings, which is convenient for users to recall historical data and reduces the time for data recording.

Backlight and Hold Function: The backlight provides auxiliary lighting for use in dimly lit environments. The hold function can fix the current pressure value, which is convenient for users to read and record.

Over - pressure Alarm: It has visual and audible over - pressure alarms, which can remind users in time when the measured pressure exceeds the set range, ensuring the safety of the instrument and the measured system.
