Dwyer solid plastic portable manometers are precision instruments in inclined and vertical (well-type) styles for the measurement of static pressure, vacuum or differential pressure. Suitable for Total Pressures Up to 100 psig, Temperatures Up to 150°F, Accuracy ±2% of Full Scale (1% on Model 115 Only).

3 in 1 instrument possessing a digital display gauge, control relay switches, and a transmitter with current output. Is ideal for pressure, velocity and flow applications, achieving a 0.5% full scale accuracy on ranges from 0.25 to 100"w.c. Two SPDT control relays with adjustable dead bands are provided along with a scalable 4-20 mA process output.
