Differential pressure gauge ±0.138 bars with 2 inputs

This pressure gauge measures the pressure on 1 input or the differential pressure of 2 inputs (identified as + and -).
You have the choice of 11 easily selectable measurement units by successive presses on the 'units' button: kPa, psi, kgf/cm², oz/in², bar, mbar, inHg, mmHg, inH₂O, ftH₂O, cmH₂O.

The reduced measurement range is particularly suitable for experiments such as Venturi, Pitot, or Bernoulli's principle.

The pressure gauge includes the following functions:
- 11 selectable measurement units: kPa, psi, kgf/cm², oz/in², bar, mbar, inHg, mmHg, inH₂O, ftH₂O, cmH₂O
- Differential pressure measurement
- Maximum/minimum/average reading recording function
- Dual backlit large LCD screen
- Zeroing, offset compensation, and data compensation
- Low battery display and automatic power-off function
- Measurement hold and error code function
- Exceeding indicator (high and low levels)
- Recalibration by push button at any time
