DIGITAL MANOMETER MODEL DM-3700

Overview

●Sensors available for differential pressure, gauge pressure, pressure/vacuum, and absolute pressure.

●The absolute pressure and pressure/vacuum are optional.

●Covers wide range from 200 Pa (Micro) to 50 MPa (Extremely High).

●Comparators, Auto-Zero, Reading Holds, etc.

●ISO/IEC 17025 calibration required by TS16949 available.

●External sensor optionally available, which allows shorter piping to the DUT.

●Portable and fixable with dedicated brackets.

●Multi-power supply: 100 to 240 VAC
