Description
The Dwyer LPG4-D8122N is a rugged, reliable low pressure gage engineered for demanding HVAC and industrial applications where accurate measurement of low-range gas or air pressure is critical. With a 0 to 15″ W.C. (water column) measurement range and ±1.5% full-scale accuracy, this gage delivers dependable readings in a compact, field-ready package.
Constructed with brass and beryllium copper wetted materials, the LPG4-D8122N resists corrosion and ensures long-term durability in contact with process media. The drawn steel housing features a protective black finish, and the NEMA 3 enclosure rating provides resistance to falling dirt, rain, sleet, snow, and windblown dust — making it well suited for both indoor and outdoor installations.
The 2-1/2″ dial face offers a clear, easy-to-read display, while the 1/4″ Male NPT connection simplifies installation into standard piping systems.
