The Testo 515 Ex provides fast, precise leak detection down to 1 g/a with response times under 2 seconds. Its flexible gooseneck ensures safe measurements in tight spaces, while colour and trend displays support accurate pinpointing.
With interchangeable sensors for refrigerants and flammable gases, and ATEX certification, it delivers reliable performance in demanding, hazardous environments. Leak rates down to 1 g/a can be detected, ensuring high sensitivity and long-term sensor stability. Advanced fan suction delivers response and recovery times of less than 2 seconds, enabling fast leak localisation. The flexible gooseneck allows safe, reliable detection even in tight or difficult-to-access areas.
Selectable display modes with colour graph and trend curve visualisation enable clear monitoring of leak progression and precise pinpoint detection, and interchangeable sensors enable 2-in-1 detection of refrigerants and flammable gases. ATEX certification ensures safe, reliable operation in potentially explosive environments.
⚠️ Per Testo's own instruction manual: this device is designed for rapid leak detection and is not suitable for precise concentration measurement. Do not charge in explosive environments, and use only the original Testo power adapter.
A single instrument capable of detecting both refrigerants and flammable gases via interchangeable sensors saves carrying two separate leak detectors, and 1 g/a sensitivity with sub-2-second response gives genuinely fast, precise pinpointing on site. ATEX certification is essential rather than optional for work in potentially explosive environments, and the flexible gooseneck gets into tight spaces a rigid probe simply can't reach.
