 *Not recommended for oxygen service

  • Large format mechanical gauge replacement for a fraction of the cost
  • Basic digital pressure gauge

Every WT Series Panel Mount Digital Pressure Gauge comes with an ISO 17025 calibration report - NIST traceable, A2LA accredited, internationally recognized by ILAC - with test data at 5 temperatures, proving our gauges meet specifications throughout their full temperature range.  



*Not recommended for oxygen service

Specifications include all effects of linearity, hysteresis, repeatability, temperature, and stability for one year.


20% to 100% of Full Scale: ±(0.1% of Reading).

Unneeded pressure units may be disabled via the RS-232 connector using ConFigXP software. • kPa models can display pressure in kPa and bar (or mbar) only. PSI and bar models can display all available units. • A WT gauge will indicate pressure up to 10% above Range Pressure. Above 110%, the WT 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 only on WT Series gauges with ranges of 2000 PSI and higher.
