Differential, High Accuracy, Digital Pressure Gauge With Output

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 gage. You get all the durabilty and stability of the micromachined silicon sensor in a rugged NEMA 4X (IP65) package.
