Tracing a small gas leak back to its source is far easier with an instrument that responds instantly and localises precisely — which is exactly where the testo 513 is built to perform. It detects methane, propane, butane, and hydrogen, with a response and recovery time under 2 seconds, so an engineer can sweep a joint or fitting and get an immediate, reliable reading rather than waiting for the instrument to catch up.
The flexible gooseneck probe reaches into awkward pipework and fittings without contorting the whole unit, and pinpoint mode combined with automatic zeroing narrows a leak down to its exact source rather than a general area. At its most sensitive setting, the 513 can detect leaks as small as 3 g/a — the kind of leak that's easy to miss with a less sensitive instrument but still worth finding before it becomes a bigger problem.
The sensor is user-replaceable, rated for roughly two years under normal use, which keeps the instrument in service without needing to send it away for a full service or replacement.
Sub-2-second response and recovery means you can move quickly along a run of pipework without second-guessing whether a reading is real or lag from the previous test point, and the 3 g/a sensitivity catches leaks a less sensitive detector would miss entirely. Being able to replace the sensor yourself also means the instrument stays in daily use rather than sitting with a manufacturer for a service.
