The LF101A Leaf Wetness Data Logger is a complete solution for accurately measuring and recording leaf wetness conditions. Designed to respond to environmental conditions similarly to a natural leaf, the sensor detects both the presence and amount of moisture and can also identify ice formation.
Ideal for plant disease forecasting, irrigation studies and frost cycle monitoring, the LF101A includes a data logger, weatherproof enclosure and leaf wetness sensor for a ready-to-use monitoring system. With storage for up to 1 million readings, ultrahigh-speed data download, multiple start/stop functionality, optional memory wrap and password protection, programmable alarms and a battery life indicator, the LF101A provides reliable, flexible monitoring for agricultural and environmental applications.
