DIGITAL PRESSURE METERS

The Model DPM-2250 Series is a Microprocessor based High Precision Differential Digital
Pressure Meter Family. They measure both gas and liquid pressures and provide multiple
engineering unit displays for the results. The units can have one pressure sensor with two
ports. The optional features of storage of min and max pressures and an RS232 port are
available. In addition, an optional temperature sensor input can be added to measure
pressure and temperature all in one meter. The following are highlights of some of the main
features.

DPM-2251 (Basic Features):

• LARGE GRAPHICS DISPLAY WITH CURSOR SELECTION OF
OPTIONS AND SETUP OF PARAMETERS

• 0.05% FS PRESSURE ACCURACY

• STANDARD PRESSURE SCALES INCLUDE 8 DIFFERENT

ENGINEERING UNIT RANGES
(PSI, mmHG, inHG, cmH2O, inH2O, Kpa, Bar, mBar)

• DIGITAL CALIBRATION – NO POTS TO TURN

• SELECTABLE DISPLAY OPTIONS AND DIGIT SIZES

• BATTERY LIFE DISPLAY (0 to 100%)

• PROGRAMMABLE DIGITAL FILTER

• CONTRAST IS SOFTWARE ADJUSTABLE

• 16 BIT MEASUREMENT

• DIGITAL ZERO ADJUST

• DC OUTPUT (OPTIONAL)

DPM-2252 ADDS:

• MAX and MIN PRESSURE VALUE STORAGE

• RS232 SERIAL COMMUNICATIONS

TEMPERATURE OPTION ADDS:

• YSI 700 TEMPERATURE PROBE INTERFACE

• -20.0 TO 100.0 C / -4.0 TO 120 F TEMPERATURE RANGE

• 0.5% FS ACCURACY

• MAX and MIN TEMPERATURE VALUE STORAGE
