Metric, High Accuracy Digital Pressure Gauge With Output

Omega’s DPGM409 digital pressure gauge incorporates a rugged 316 SS enclosure designed for washdown and marine applications with a precision 0.08% accuracy pressure transducer with 316L SS wetted parts and body. The result is an extreamly durable digital pressure gage designed to survive harsh industrial environments. The large 25 mm (1′) display is easy to read at a distance up to 11 m (36′). Models are available in Gauge, Sealed Gauge, Compound Gauge, Absolute, Vacuum and Barometric pressure ranges. Standard features include a highly stable silicon sensor, selectable MIN/MAX and AVG readings, Hi and LO alarms and an externally powered user selectable analog output. An optional wireless transmitter feature with software allows the signal to be transmitted to a remote location such as a PC for charting and data logging. Power is from an internal long life battery (included) or an eternally supplied dc voltage source. Free downloadable software allows the user connect to a pc via a standard USB connection (cable included) and select a variety of user configurable features including update rate, dampening, units, backlight and auto off.

NOTE: Models with wireless option are approved for use in the U.S., Canada and Europe only.
