D31 DIAPHRAGM TYPE MECHANICAL DIFFERENTIAL PRESSURE GAUGE
Fillable
The Reotemp Series D31 diaphragm-type differential pressure gauge is a proven choice for filtration monitoring, flow measurement, and HVAC system applications. It’s especially suited for high static pressure applications where no migration of process media between the high and low sides is permitted. A rolling diaphragm, magnet, and calibrated rotary movement isolate the media while delivering accurate, repeatable readings.
