testo 515 Ex - Multi-purpose leak detector – Refrigeration

The testo 515 Ex provides fast, highly sensitive leak detection down to 1 g/year, with response times of less than 2 seconds.
Its flexible gooseneck probe enables safe measurements in hard-to-reach areas, while clear display modes featuring colour-coded and trend visualizations support precise leak localization.

Interchangeable sensors for flammable gases and refrigerants, combined with ATEX certification, make it a versatile and safe tool for demanding environments.

Highly sensitive – Detects leak rates as low as 1 g/year, with response and recovery times of < 2 seconds
Convenient – Leak detection via a flexible and durable gooseneck probe
Simple and reliable – Selectable colour display modes (numeric, bar graph and trend curve) provide intuitive leak analysis
2-in-1 – Detects both refrigerants and flammable gases (with an additional gas sensor)

The testo 515 Ex combines fast, reliable performance with a user-friendly design.
Leak rates as low as 1 g/year can be detected, ensuring both high sensitivity and long-term sensor stability. An advanced pump-assisted sampling system delivers response and recovery times of less than 2 seconds, enabling rapid leak detection. The flexible gooseneck probe provides safe and reliable detection, even in confined or hard-to-reach areas. Selectable display modes with colour graph and trend curve visualization allow clear monitoring of leak development and precise leak localization. Interchangeable sensors enable 2-in-1 detection of both refrigerants and flammable gases.
ATEX certification ensures safe and reliable operation in potentially explosive environments.
