Thanks to its particularly ergonomic shape the HL 50-BT is a single hand operated instrument.
Two operation buttons and a thumb - that‘s all you need to use the HL 50-BT.
In the standard version, the HL 50-BT offers an integrated sensor and bluetooth headphone.
There are no irritating connection cables. The HL 50-BT therefore offers optimal mobility and is
highly suitable for listening to valve spindles and hydrants, but also to fittings in buildings.
A large LCD display shows the measured sound level simultaneously in numerical form and
as a bar graph. In addition, the currently set frequency filter is displayed. When a measurement
has been completed, the previous measured sound level is indicated on the bar graph.
For great flexibility and professional use, three optional external microphones are available for
the HL 50-BT.
