The Testo 515 Ex combines fast and reliable performance with user-friendly design. Leak rates down to 1 g/a can be detected, ensuring high sensitivity and long-term sensor stability. An advanced fan suction delivers response and recovery times of less than 2 seconds, enabling fast leak localization.
The flexible gooseneck allows safe and reliable detection even in tight or difficult-to-access areas. Selectable display modes with color graph and trend curve visualization enable clear monitoring of leak progression and precise pinpoint detection.
Interchangeable sensors enable 2-in-1 detection of refrigerants and flammable gases (with additional Refrigeration sensor). UL/CSA/SGS certification ensures safe and reliable operation in potentially explosive environments.
