The Model BDG-01 Brass Digital Pressure Gage measures gas pressure with
±0.5% of full-scale accuracy at an affordable price. With brass wetted material, the
Model BDG is designed for your specific applications of compatible gasses. Its design allows for easy installation. User-selectable units of measure let one gage be used for various pressure scales.
Location
Select a location where the gage can be easily read and the temperature will not exceed 140°F (60°C). The mounting surface to the gage should be free from excessive vibration.
Installation
When installing the gage, always use 7/8˝ hex wrench at the base of the housing to tighten the gage to a mating fitting. Be sure to use proper thread sealant when installing. Do not apply wrench to housing.
