Zero

Zero pressure correction (gauge/differential sensors)

Tare

0 to 100% FS temporary zero offset capability by subtracting the current reading from subsequent measurements.

Filter

Enables a filtered pressure reading by showing a rolling average of the last 10 measurements. Providing a more stable reading of a noisy measurement.

Special Features

Pressure Units

mbar, bar, Pa, hPa, Pa, MPa, psi , lb/ft2, kgf/cm2, kgf/m2, mmHg(0°C), mHg(0°C), inHg 0, mmH2O, cmH2O, mH2O, inH2O (4°C, 20°C), ftH2O (4°C, 20°C)

Calibration Certificates

• Supplied as standard with bar, psi and kPa

• Optional UKAS approved calibrations available

Leak Test

Used to determine if there is a leak in the system by recording the pressure change over of time.

Leak test can also be used with the RTD sensor to record a temperature change over time.

User defined 1, 3 or 5 minute leak test.

Alarm

User adjustable; high and low pressure alarms with visual (Bell Icon, Pressure Reading and Backlight flash) and audible warning for 60 seconds.

Calibration

Used in conjunction with the optional pneumatic or hydraulic hand pumps, the DPI 705E Series provides a simple, low-cost calibration solution.

Battery

• 4 x AA Alkaline/NiCd/NiMH cells

• Power efficient design, can be used for 8 Hours per day, 6 days per week for 1 Yearusing a single set of batteries.

Maximum/Minimum

Captures both maximum and minimum readings in peak-hold mode.

Display

16mm LCD with ±99999 readout
