SHARE

Positioned amongst cuttings this unit is a moisture sensor which determines the frequency of misting. Moisture on the surface of the detector carries a current between its two electrodes. When the water has evaporated the circuit is broken, sending a signal to the Mist Control Unit, causing misting to commence. The Electronic Leaf is supplied with a choice of 2.5m, 5m or 10m cables to suit the individual bench requirements.
