Dwyer Instruments 490W-6-INT-NIST | Hydronic differential pressure manometer | Full kit with (2) each 200 psi sensors with NIST calibration - INTL VERSION
The most precise and user-friendly manometer available is the Series 490W Wireless Hydronic Differential Pressure Manometer. A single operator may monitor and balance a hydronic system faster than with typical hydronic balancers by utilizing wireless transducers and a mobile device. The Series 490W transducers allow you to monitor differential pressure and flow on up to three separate valves by connecting wirelessly to a UHH6 or newer portable device or your own mobile device. Due to their wireless nature, there are no hoses to carry, snag on gear, or need to be emptied. The 490W uses Dwyer's hydronic application software, which translates differential pressure to flow immediately on the screen and includes valve charts for many manufacturers.
