Working leak detection in or near a potentially explosive atmosphere calls for an instrument built for that environment from the ground up, not adapted to it — which is exactly what ATEX certification on the testo 515 Ex delivers. It detects leak rates as low as 1 g/a, with response and recovery times under 2 seconds thanks to an advanced pump-assisted sampling system, so a technician gets a fast, confident reading rather than waiting out a slow sensor.
The flexible gooseneck probe reaches into tight or awkward fittings safely, and the colour display — offering numeric, bar graph, and trend curve views — makes it straightforward to watch a leak's progression and pinpoint its exact source rather than a general area. Supplied here with the refrigerant sensor, this variant detects HCFC, HFC, HFO, HCFO, HC (R290), and blends. Interchangeable sensors give the 515 Ex genuine 2-in-1 flexibility, with the additional gas sensor extending coverage to flammable gases when needed.
ATEX certification isn't a nice-to-have on this instrument — it's what makes leak detection in a potentially explosive atmosphere possible at all, and the 1 g/a sensitivity catches leaks a lower-spec detector would miss entirely. Supplied with the refrigerant sensor, it's ready for refrigeration work out of the box, with the option to add the gas sensor later rather than needing a second dedicated instrument.
