Ultra rugged, intrinsically safe, digital test gauge with 0.1% of reading accuracy.

  • Marine grade enclosure resists corrosion
  • Accuracy not affected from -10 to 50°C
  • Replaces 5 or more digital test gauges 
  • Fast pressure safety valve (PSV) mode
  • Define custom pressure units
  • Shift everyday wear to replaceable CPF adapter 
  • Easy to use-No Menu. No Manual? No Problem!

With the optional DataLoggerXP upgrade:

  • Record 32 000 data points
  • Battery-optimizing, Ultra Low Power (ULP) Mode
  • Over an entire year of continuous recording time
  • Now available on the Dual-Line Display XP2i

Starting in January 2017, new XP2i gauges include a signal that will warn users when the gauge calibration is about to expire. Using our free ConFigXP software, the gauge can be programmed to alert you prior to, on, and after the gauge’s calibration due date.

They can even select the type of alert you want from a start-up warning to a continuous warning which does not allow the user to operate the gauge.


  • Field gauge calibration
  • Permanent outdoor installation

The following requires the use of our free ConfigXP software.


User Defined Unit: Allows the user to define and display any pressure units not included, or to use the gauge to display force, level, or other pressure related parameters. Reduce or increase displayed resolution.
PSV Mode: Intended for pressure safety valve / burst disk testing. 8 readings per second. Captures point at which valve opens, as well as reseat pressure.
Averaging: Smooths unsteady readings (1 to 10 samples).
Remove: Unwanted pressure units from Units button.
Disable: Peak pressure button.
Limit or Disable: Zero button.
Password Protect: Changes to configuration or calibration factor(s).
Save: Configuration to a file.
Copy: Configuration to other gauges.

XP2i complies with the Electromagnetic Compatibility and the Pressure Equipment Directives. Refer to the EC Declaration of Conformity for specific details.


The instrument was tested against AS/NZS 3584, C-tick EMC/EMI requirements.


XP2i is approved for use a portable test instrument for Marine use and complies with Det Norsjke Veritas' Rules for Classification of Ships, High Speed & Light Craft and Offshore Standards.

Unneeded pressure units may be disabled via the RS-232 connector using ConFigXP software. • kPa and MPa models can display pressure in kPa, MPa, and bar (or mbar) only. PSI and bar models can display all available units. • An XP2i will indicate pressure up to 10% above Range Pressure. Above 110%, the XP2i display will flash, indicating that the applied pressure exceeds the calibrated pressure range. If the calibrated pressure range is exceeded, the pressure displayed may not be accurate.  • An Absolute version is available for XP2i gauges with ranges of 2000 PSI and higher.
