DP 210 Digital Pressure Meter

Differential, Static & Peak Pressure
with Printer output

The DP 210 series hand held pressure meter features

microprocessor based linearization for excellent
accuracy over the entire pressure range allowing you
to measure and display in any of four common
engineering units. In addition peak pressure and
pressure differential are also shown.

The 4 line x 20 character LCD screen displays

pressure readings from pressure input P1, Input P2
and the difference (P1-P2). Peak pressure readings
for P1 and P2 can be switched ON/OFF. Pressure
readings can be changed to reading bar, psi, mps
(megapascals) and ksc (kilograms/cm2).

Two pressure transducers are housed inside the

rugged metal case. This configuration protects the
transducers from damage as well as assuring
consistent temperature stability. Pressure connections DP 210
to the hydraulic system are made with two hoses and
mating quick disconnect couplings.

A 9 pin printer output port is also provided which Features
