Greisinger GMH 3161-07 WPD5 differentiaaldrukmeter, -10 tot 350 mbar 604190

Measures differential pressure from -10.00 to 350.0 mbar with 0.01 mbar resolution and ±0.1 % FS accuracy, ideal for precise air pressure monitoring.

Overview

The Greisinger GMH 3161-07 is a handheld differential pressure meter featuring an internal WPD5 piezo-resistive sensor. It displays readings on a 4½ digit LCD with backlight and offers selectable units including mbar, hPa, Pa, kPa, mmHg, PSI, mmH2O, mH2O, inH2O, and ftH2O. The device supports min/max memory, hold, tare, zero point adjustment, and auto-off functions. It is powered by a 9V block battery or external 10.5-12V DC, with a battery life of approximately 150 hours without backlight. The front panel is IP65 protected, and the housing is impact-resistant ABS plastic. Pressure connections are two universal nozzles of 5 mm diameter. The meter has a serial RS232 interface for data communication and a response time of less than 1 second.
