The Dierential Pressure Manometer (dpm) is a rugged,
digital instrument used to measure the pressure drop or
pressure gain across hydronic system components. The
dpm is available in either 0-15 psi or 0-100 psi measurement
range models for precise adjustment of circuit balancing
valves, and to monitor circulator performance. Both models
measure gauge or dierential pressure and can store up to
40 readings for later recall. The operator can select from
a variety of Imperial and metric measurement units to suit
the hydronic system design data. Valuable safety features
include visible and audible instrument over-range warning
alarms and backlit display for work in poorly illuminated
areas. The lightweight, compact dpm design is easy to
use in the tight, overhead spaces commonly encountered
when balancing or troubleshooting hydronic systems.
