USB
The wired version offers a solid method for performing a leak test and has the same features as the Bluetooth® version. However, this type is connected by a USB cable and has the advantage of a fixed power supply and a cheaper price. Measurements can be taken using a desktop or laptop, but also with Android tablets or smartphones with the so-called “USB On-The-Go” specification (OTG) and can therefore function as a USB host.
