NEMA 4X (IP65) Enclosure
OMEGA’s DPG409 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 durabilty and
stability of the micromachined silicon
sensor in a rugged NEMA 4X
(IP65) package.
