Description

The SC77 Low Range Differential Pressure Wireless Sensor can monitor a number of critical room environment applications including research and storage areas as well as hospital laboratories, operating, isolation and clean rooms. The SC77 precisely monitors the differential pressure between two rooms or air spaces down to 2.5 Pa (0.01 in H2O) across a range of +/- 250 Pa (+/- 1 in H2O). The two nipple fittings on the case can be connected to the two airs paces using the included tubing, allowing the sensor to measure differential pressure between the two sources. Other typical differential pressure requirements are found in electronics production clean rooms, construction areas, air handlers, filtration systems and pitot tube sensors.
