handheld automotive multimeter ADM5201

The ADM5201 advanced handheld automotive multimeter combines all the features of a full function multimeter and integrates the functions of an O2 Sensor tester, PFI & TBI Fuel Injection tester. The ADM5201 provides a quick and accurate diagnosis of the complete O2 circuit. It is also capable of sending a Rich/Lean signal to the ECM, and displaying crossing-per-second (CC) and O2 voltage simultaneously, when secondary display shows test results. This professional grade multimeter provides efficient trouble shooting solutions to the most difficult problems encountered in today's sophisticated automotive electronic systems.

The ADM5201 has a bright LED backlight. A battery access door allows users to replace the battery and fuse without breaking calibration seals! High impact over-molded case absorbs shock over more of the case than a conventional rubber boot design. Convenient closed case calibration allows adjustments to be made directly through the Optically-Isolated RS232 serial port.  Three year limited warranty.
