NOX TESTER
This diagnostic tool tests NOx sensors by connecting to the sensor's circuit board and probe. It activates the sensor, collects data on NOx and oxygen levels for three minutes, and analyzes the results to identify faults and generate a report.
- Connects to NOx sensor via diagnostic harness
- Communicates via CAN signals
- Tests sensor circuit board and detection probe
- Activates NOx sensor
- Collects NOx and oxygen concentration data
- Analyzes data and generates test reports

The NOx SENSOR TESTER is a specialized testing device for NOx sensors. It connects to the sensor via a dedicated diagnostic harness. The self-developed APP+ diagnostic device communicates with the NOx sensor via CAN signals, testing the sensor circuit board and detection probe. Upon successful communication, a working command can be sent to activate the NOx sensor. The probe will then start heating up and, once it reaches its operating temperature, will continuously collect NOx values and oxygen concentration. The testing process takes 3 minutes, during which the device analyzes the collected data to determine the sensor's condition, identifies the cause of any faults, and generates a test report.
