The SDT270 is a special tank system that is used for measuring the tightness and control on underground units like tanks and their accompanying pipes. This method is widely used as and relied on. This works on the principal that when the vacuum is created inside, a sound is created while helps in giving us the correct data and is also very cost-efficient as well. It is a very simple and accurate method to get the results.

Along with this device additional SDT270 TankTest Reporter software is included which automatically creates the details and the result which are absolutely accurate. The outputs are all stored in the detector which can subsequently be transferred to the personal computer.The results provide evidence to the testing measurement reading as well as the graphics. It can also archive performances.

The control principal is such that a vacuum pump creates a pressure which is reduced in the tank leading to the acoustic vibrations in the wateror air or any other substance from a whole in the tank wall. It can be detected by 2 levels.
