The RPT-5 device is used to perform independent, parallel pressure measurement in storage fuel systems such as Common Rail (Diesel) and GDI/FSI (petrol). In addition to the pressure value, the tester also diagnoses the sensor power supply. An additional advantage is the ability to automatically recognize the sensor's pinout system, especially useful when using needle probes.

The device can be used to test injection systems:

- passenger cars,
- trucks and buses,
- tractors and agricultural machinery,
- construction machines,
- power generators.
