About NOX TESTER
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.
