With multiple accessories for various tasks, our LD-12 water leak detector rental kits are the complete tool for leak surveying and pinpointing. Surveying is fast and efficient using the magnet base for a quick sensor attachment to hydrants or valves. A contact rod is also included and useful for below grade water meters and fittings. For exact leak pinpointing, the ground plate allows listening along concrete or slabs while standing up. The amplifier itself features powerful options like easy to select filters for blocking out background noises, a limiter switch to protect hearing, and a large analog sound level gauge.
