8900 0501 Sensor LD pro ultrasound detector set by Testo
Gases escaping from leaks in pipe systems (e.g. corrosion, leaky screw connections, etc.) cause noises in the ultrasonic range. With the testo Sensor LD pro ultrasonic detector kit, even the smallest leaks, which are not audible to the human ear and not visible due to their size, can already be localized from several metres away. The testo Sensor LD pro converts the inaudible ultrasound into audible frequencies. These sounds can be perceived even in noisy environments with the sound-proof headphones that are comfortable to wear.
The testo Sensor LD pro ultrasonic detector kit impresses thanks to its high-precision sensor technology and improved support in the detection of leaks (e.g. in compressed air, gas, steam and vacuum systems, refrigeration systems, door seals). The leak can be more accurately localized thanks to the integrated laser pointer which acts as a sighter.
The leakage data can be transmitted to the Testo Leak Software via a USB interface. Once the data have been exported to the software, clear reports can be created for documenting the leaks that have been found.
- Improved localization of leaks thanks to sound funnel
- Robustness and a low weight ensure non-tiring use in industrial environments
- Continuous operation for 9 hrs
- Easy operation via touchscreen
- With integrated camera: display and storage of leaks in the image
- Direct display of the leakage rate in l/min and the costs in EUR
- Transmission of leakage data to the PC via USB
- Easy creation of a report in accordance with ISO 50001 with the Testo Leak Software
