OMEGA’s DPGM409 digital
differential pressure gauge
incorporates a rugged 316 SS
enclosure designed for washdown
and marine applications with a
precision 0.08% accuracy pressure
transducer and 316L SS wetted
parts and body. The result is an
extremely durable digital pressure
gauge. You get all the durability
and stability of the micromachined
silicon sensor in a rugged NEMA 4X
(IP65) package.
