Description
The Amprobe AU92 automotive multimeter is a full-featured multimeter that offers additional measurements specific to automotive servicing. Ideal for locating faulty wiring and components, the AU92 has all standard multimeter functions such as voltage, current, resistance and continuity. The meter includes a built-in thermometer to measure air, surface or immersion temperatures and also tests engine RPM and dwell. An Inductive Pickup tool allows for accurate RPM measurements for 2 and 4-stroke automotive engines.
The Amprobe AU92 automotive multimeters are rugged and lightweight making them ideal for use either in the shop or in the field. A magnetic hanging strap keeps the meter handy. Results are clearly shown on the 3-3/4-digit LCD. The meter also includes a data hold function, auto zero, low battery indication and auto power off. The Amprobe AU92 automotive multimeter has a CAT III-600 Volts AC & DC rating.
Amprobe AU92 automotive multimeters ship complete with:
- Inductive pick-up probe
- Carrying case
- Test leads
