The testo 514 is a reliable, easy‑to‑use detector for pinpointing even the smallest refrigerant leaks in AC/R systems. 
With 3 g/a sensitivity and testing according to DIN EN 14624, it meets EU F‑Gas requirements while delivering precise results. 
Ready to use immediately without selecting a refrigerant type, and featuring a replaceable sensor, it ensures efficient work with minimal downtime.

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 color 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.

The testo 515 Ex offers fast, highly sensitive leak detection down to 1 g/a with response times under 2 seconds. Its flexible gooseneck enables safe measurements in hard‑to‑reach areas, while clear display modes with color and trend visualization 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.

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.

With a sensitivity of 1- 3 g/a (depends on device version) and a response time below two seconds, it quickly identifies even small leaks during routine service work, ensuring dependable performance in everyday HVAC/R applications.

The Basic Combi Refrigeration Sensor delivers fast and reliable leak detection for all common refrigerants when used with the testo 514 or testo 515 Ex.
