Sealey TA302 12 Function IC Digital Automotive Multimeter

The Sealey TA302 is a 12-function automotive diagnostic multimeter designed specifically for vehicle testing and diagnostics. This auto-ranging digital multimeter features a combination digital and bar graph display, providing accurate real-time indication of component outputs crucial for automotive fault-finding and electrical system testing.

Built for the demands of professional workshops, this automotive multimeter reads standard vehicle parameters including duty cycle, dwell angle, and engine RPM across 4-8 cylinder configurations. The large 18mm high-contrast display incorporates a bright white backlight for easy reading in low-light conditions under bonnets and dashboards, while the workshop-tough hi-impact case with integral stand ensures durability in demanding garage environments.

The TA302 features comprehensive auto-ranging functionality across voltage, current, resistance and frequency measurements, eliminating manual range selection and speeding up diagnostic work. Overload protection on all ranges safeguards the meter during testing, whilst the data-hold function allows readings to be frozen for recording. The unit measures DC voltage up to 600V, AC/DC current up to 10A, resistance to 32MO, and temperature from -20°C to +760°C, covering the full spectrum of automotive electrical diagnostics.

Supplied complete with inductive coupler for non-contact RPM measurement, test probes for direct electrical testing, and a thermocouple for temperature measurement. The continuity buzzer (activated below 35O) provides instant audio feedback during circuit testing, whilst diode check functionality supports electronic component diagnostics. A 9V PP3 battery is included with low battery indication to prevent unexpected power loss during critical testing.
