General function description

4 General function description
When gases escape from leaks in piping systems (leaking screw connections, corrosion, etc.), noises are
generated in the ultrasonic range. With the Testo Sensor LD pro even the smallest leaks, which are
inaudible to the human ear and not visible due to their size, can be located several meters away.
The inaudible ultrasound is converted to audible frequencies in addition to the display emission level
shown in the display. With the convenient, sound-proof headphones, these sounds can be heard even in
noisy environments.
In addition, the new Testo Sensor LD pro calculates the cost associated with leaks, providing additional
transparency about the state of the system under test or the potential cost savings.
The loss is displayed in l / min as well as in a freely selectable currency. The cost per liter or per cubic
meter of compressed air can be stored in the device.
The professional measuring instrument Testo Sensor LD pro finds typical application in leak detection in
compressed air systems.
With the help of an integrated laser pointer, which serves as a targeting device, the leak can be
pinpointed.
Depending on the leakage, the appropriate accessories may be used to increase the sensitivity of the
Testo Sensor LD pro, available accessories are:
 Acoustic trumpet
 Focus tube with focus tip
 Gooseneck
 Parabolic mirror
Note:
To use the parabolic mirror and gooseneck, these components must be activated during initial
commissioning in order to save the component-specific adjustment parameters. If this has not
already been done ex-works, the data for this is supplied via USB stick. For the activation
(parameter import), see chapter „Import measurement tool".
