BDG BDGWDG WDG

The Series BDG-01 Brass Digital Pressure Gage measures gas pressure with
±0.5% FS accuracy at an affordable price. With brass wetted material, the series BDG

is designed for your specic applications of compatible gases. Its design allows for

easy installation. User-selectable units of measure let one gage be used for various
pressure scales.

The Series WDG Weatherproof Digital Pressure Gage measures gas and liquid
pressure with high accuracy at an affordable price. It’s rugged weatherproof design

stands up to outdoor and industrial environments. The 4-digit backlit display with four
selectable units makes readings easily visible to prevent reading errors. The WDG

comes with 304L stainless steel wetted material for a wide range of compatible liquids
and gases.
