Description

The Sealey TA304 is a professional 15-function automotive diagnostic multimeter designed for comprehensive vehicle system testing and fault diagnosis. Combining auto-ranging digital measurement capabilities with an infrared thermometer attachment, this versatile analyser delivers the precise readings essential for modern automotive diagnostics. Built for the demands of busy workshops, the TA304 features a workshop-tough, durable case with integral stand and bright white backlit display for clear visibility in all lighting conditions. The combination digital and bar graph display provides accurate indication of component outputs, whilst high-speed processing circuitry reads critical automotive parameters including duty cycle and pulse width—making this tool particularly effective for testing fuel injection systems, ignition components and electrical circuits. The auto-ranging functionality eliminates manual range selection across all measurement types, whilst data-hold, min/max and peak hold functions capture readings for analysis. Overload protection on all ranges ensures safe operation, and the auto-power shut-off conserves battery life during extended use. This comprehensive diagnostic tool is ideal for professional mechanics and automotive technicians requiring a single instrument for electrical system diagnostics, ignition timing checks, temperature monitoring and circuit testing. The included inductive coupler enables non-intrusive RPM and dwell angle measurements across 2-10 cylinder engines, whilst the infrared temperature probe and thermocouple provide contact and non-contact temperature measurement options up to 760°C. Features and Benefits: • 15 measurement functions including voltage, current, resistance, capacitance and frequency • Dedicated automotive parameters: tachometer (600-12000rpm), dwell angle for 4/5/6/8-cylinder engines • Dual temperature measurement: infrared probe (-20 to +280°C) and thermocouple (-20 to +760°C) • Auto-ranging on all functions for fast, error-free operation • Data-hold, min/max and peak hold functions for capturing intermittent faults • Large 20mm digit height display with bar graph and bright white backlight • Complete kit supplied with inductive coupler, probes and storage case • Compact 182 x 82 x 55mm size with integral stand for hands-free operation Specifications: Brand: Sealey Nett Weight: 360g Tach (rpm): 2-10Cyl, 4-Stroke 600-4000 (x1)rpm, 600-12000 (x10)rpm Dwell: 4Cyl 0-90°, 5Cyl 0-72°, 6Cyl 0-60°, 8Cyl 0-45° AC Voltage: 400mV, 4V, 40V, 400V, 700V (Auto-Ranging) DC Voltage: 400mV, 4V, 40V, 400V, 1000V (Auto-Ranging) AC Current: 400µA, 4000µA, 40mA, 400mA, 4A, 20A (Auto-Ranging) DC Current: 400µA, 4000µA, 40mA, 400mA, 4A, 20A (Auto-Ranging) Capacitance: 40nF, 400nF, 4µF, 40µF, 400µF, 4mF, 40mF (Auto-Ranging) Frequency: 0.001Hz-9.99MHz (Auto-Ranging) Duty Cycle: 0.1-99.9% Pulse Width: 0.1-10ms Resistance: 400O, 4kO, 40kO, 400kO, 4MO, 40MO (Auto-Ranging) Continuity:
