This category covers meters and testers for electrical fault finding on vehicles, machinery and installations. The Multimeters page lists digital multimeters in manual and auto-ranging versions, pocket and analogue meters, models with thermocouple temperature measurement, clamp meters and current clamps. Automotive testers are also included, such as glow plug testers, lambda sensor testers, key fob testers, integrated test lights with voltmeters and digital thermometers with probes.
Brands include Sealey and Draper. Auto-ranging meters select the measurement range automatically, which speeds up routine checks, while manual-ranging meters give direct control of the range. Compare the number of functions against the tests you carry out, and choose a clamp meter or current clamp where current needs to be measured without breaking the circuit.
