New from Gunson is this super-versatile Spark Plug Tester (part number 77176), a mains-powered diagnostic tool tailored for both professional and home mechanics as well as classic car enthusiasts. The tester replicates engine RPM and enables easy visual assessment of spark plug condition and performance.

The simulated RPM output is easily adjusted from 1000rpm to 6000rpm, testing the spark plug throughout this rev range; a plug may seem to be sparking adequately at cranking or idling speeds but breaks down at higher RPM. Importantly, with dual testing ports, users can easily compare two spark plugs simultaneously, assisting in diagnosis. A brand-new plug can be compared with an existing plug removed from the engine, for example.

For added safety, the unit is equipped with a clear protective guard with a hinged design to safeguard users from electrical hazards. It operates with an AC power input (100-230V) and delivers a 12V/1A DC output to the tester, meeting CE and RoHS compliance standards. The tester comes complete with a UK 3-pin plug and EU mains adaptor for international compatibility.

Now available for purchase at Gunson Tools’ stockists and online tool retailers.
