Precision Instruments for Pressure, Flow, Temperature and Level

The Meridian Model 40GD10 Inclined Tube Manometer provides accurate measurement of low pressurea, drafts, and small differential pressure changes, as in air or gas flow metering. It is available in six ranges and in both left zero and intemediate zero models. This design assures long-time accuracy and repeatability for accurate low pressure measurements. Each guage is individually factory calibrated before shipment.
