automotive exhaust oxygen sensor tester simulator handheld zirconia titania sensor check portable lambda meter diagnostic tool all-sun em272

he oxygen sensor tester is designed to measure the crossover changes which occur in the closed loop control system.the tester can be used to analyse zirconia or titania type sensor.the tester can simulate the sensor signals to the ecu to verify acceptance of the signals and confirm that the ecu acts upon these signals. the tester allows the operator to verify which wire the tester is connected to, this is very useful when working with heated sensors.
