Oxygen Sensor Analyzer

Quickly and accurately diagnoses and simulates oxygen sensors; works on both Zirconia and Titania type sensors.
Four indicator lights guide you in connecting the proper oxygen sensor wire. No need to consult wiring diagrams.
Simulates a 5-second rich or lean signal to the ECM. Use in conjunction with your other equipment to validate operation of the entire fuel delivery system.
Provides rich/lead indication with a 20-segment bar graph. Measures the activity level of the oxygen sensors, making it easy to find lazy or inactive O₂ Sensors.
Counts the O₂ cross counts, and displays on the LED.
Internal 9-volt battery eliminates the need for power leads. Automatically powers down.
