    Extech 407910 Heavy Duty Differential Manometer

    The Extech 407910 Heavy Duty Differential Manometer measures differential pressure from 0 to ±2000mbar with a resolution of 1mbar and basic accuracy of ±2%, including hysteresis. Measurements are available in eight different units (mbar, psi, kg/cm2, mmHg, inHg, mH2O, inH2O, and atm) and pressure is measured by internal sensors from dual differential inputs.

    Two readings can be displayed simultaneously on the Extech 407910’s large digital screen. The pressure meter has a min/max recording function and a data hold facility allows the user to freeze a reading on screen, which is particularly useful when readings are fluctuating.

    The metal inputs on the Extech 407910 have quick-disconnect fittings that are easy to use and there is an RS-232 port for working with data acquisition software (not included). A protective rubber holster makes the manometer ideal for tough conditions and has an integrated stand. The unit is supplied with a hard carry case and is covered by a three-year warranty.
