Dwyer WDPM [WDPM-350] Differential Pressure Module, ±350 inH2O

Dwyer WDPM002 [WDPM-002] Differential Pressure Module, ±2 inH2O. Dwyer WDPM wireless differential pressure module transmits measurements to the Model UHH handheld to view pressure drop across filters, static pressure in ducts, and velocity pressures from pitot tubes or air flow stations. When using it with a pitot tube or air flow measuring station, the measurement can be calculated to read directly in air velocity or volumetric air flow. The module mounts in the holder on the back of the handheld, or in an optional mounting bracket.

Wireless modules can take measurements from at least 50 feet away from the base unit. An LED flashes on the top of the module to let the customer know when the module communicates with the handheld, as well as when the module's battery is low. The battery is rechargeable via the mini-USB connector on the top of the module.
