Series BDG/WDG Brass Digital Pressure Gauge

Brand: Dwyer Instruments, LLC

The Series BDG Brass Digital Pressure Gauge measures gas pressure with ±0.5% Full Scale accuracy at an affordable price.

With brass wetted material, the series BDG is designed for your specific applications of compatible gases. Its design allows for easy installation. User-selectable units of measure let one gauge be used for various pressure scales.

The Series WDG Weatherproof Digital Pressure Gauge 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.
