Testo 515 Ex combined leak detector for refrigerants and flammable gases

Testo 515 ex combined leak detector for refrigerants and flammable gases

The Testo 515 ex is an explosion-proof combined leak detector for detecting refrigerants and flammable gases. It is suitable for service and maintenance work on refrigeration, air-conditioning and heat pump systems, as well as gas installations and forming gas tests. Thanks to its high sensitivity and fast response time, even the smallest leaks are detected quickly.
