The Sealey TA203 is a professional-grade automotive multimeter designed for comprehensive vehicle diagnostics and electrical testing. This 15-function digital multimeter combines standard electrical testing capabilities with specialist automotive functions, making it an essential tool for vehicle technicians and automotive electricians. Featuring an extra-large 36mm high-contrast LCD display with bar graph and backlight, the TA203 ensures clear readings even in poorly lit workshop environments. The robust hi-impact case includes integrated probe storage and a fold-out stand, built to withstand demanding workshop conditions. Auto-ranging functionality across most measurement modes eliminates the need for manual range selection, whilst data-hold and auto-power-off features enhance practical usability during diagnostic work. The multimeter excels at automotive diagnostics with its millisecond pulse-width measurement function, ideal for accurately testing fuel injection systems, idle air control motors and electronic transmission control systems. The integrated bar graph display is essential for proper lambda sensor testing, whilst the included inductive coupler with adjustable sensitivity enables fast engine RPM readings on both 2-stroke and 4-stroke engines. Dwell angle measurement across 1 to 12 cylinders supports ignition system diagnostics on a wide range of vehicles. PC connectivity via the supplied USB interface cable allows data logging and analysis using the included Windows software, enabling technicians to document test results and track diagnostic trends. The comprehensive accessory package includes test leads with both probe and clip options, K-type temperature probe for measuring temperatures from -20°C to +760°C, and complete operating instructions.
