PCE-P50 is a differential pressure meter used to measure gauge pressure and true differential pressure in pneumatic, hydraulic, compressor and pump installations, valves, tanks and heating, ventilation and air conditioning (HVAC) systems. 11 pressure units are selectable for Imperial and Metric measurement, including bar, mmHg, ozin², kgcm², psi, inH2, kPa, ftH2O|, inHg, cmH2O and mbar.

- Pressure measuring range: 0 to 689.5 kPa / 0 to 100 psi / 0 to 6.9 bar
- Resolution: 689.5 Pa / 0.1 psi / 0.0069 bar
- Accuracy: ± 0.3% of full scale at 25°C / 77°F
