Dwyer UHH2 Portable Test Instrument

Dwyer UHH2 Portable Test instrument is a universal meter with options for differential pressure, air flow and temperature probes.  Probes are connected wirelessly over bluetooth, making functionality much more practical for the user.  Included is the Mobile Meter® Software App on an Android® based handheld.  This allows datalogging which can be downloaded after the test, eradicating the need for old fashoined “pen and paper” recording.  Wireless anemometer, hygrometer, and pressure probes communicate to the handheld using Bluetooth SIG, Inc. wireless technology and can all be displayed simultaneously. Each Dwyer UHH2 includes a handheld base unit, UHH-BTG wireless mobile gateway, two USB charging cables, charging block, mini-screwdriver, user manual, and headphones.
