Flat Roof Leak Detection

DÖLCO FD3 Electro-Acoustic with Battery

Battery-powered variant of the FD3 — for autonomous use without mains connection

The FD3 with battery is the mobile variant of the proven electro-acoustic leak detector. Identical measurement principle, identical range and sensitivity — but with a built-in battery for use without a mains connection. Particularly useful for industrial roofs, logistics centers, or distant setup points where no 230 V connection is nearby. The higher total weight (13 kg instead of 4 kg) is the only compromise — the battery makes the device heavier, but more autonomous.
