Leakage testers are used widely in manufacturing industries to check the integrity of products and improve overall product quality. Some leakage testers come with leakage clamp meters designed to measure leakage current impeccable accuracy. These leakage testers are capable of recording accurate measurements with 1 microA resolution to nail down the leakage origin. They also have an internal memory capable of storing readings up to 65,000 measurement points. For non-sinusoidal forms, these leakage testers can record true-rms measurements accurately. Leakage testers can be used to avoid incidents of unscheduled downtime and report about erratic GFCI and RCD trips without going through the hassle of taking the equipment offline. Combustible gas leak detectors are designed to factor in temperature sensitivity which translates into an audible tickler signal. These gas leak detectors are powered by 1.5 V AAA Battery batteries.
