OM-CP-LF101A-KIT

The OM-CP-LF101A-KIT is acomplete data logging system thataccurately measures and recordsleaf wetness. Not only does it recordthe presence of water but also logsthe amount of water on the sensor.The sensor responds toenvironments the same way a realleaf does and can also detect whenice is present. This low cost systemcomes complete with a data logger,weatherproof enclosure and leafwetness sensor.

The OM-CP-LF101A-KIT is ideal forplant disease forecasting, irrigationstudies and monitoring frost cycles.It features a multiple start/stopfunction, ultra-high speed downloadcapability, 1,000,000 readingstorage capacity, optional memorywrap, battery life indicator, optionalpassword protection, programmablealarms and more.An OM-CP-IFC200 interface cableand software package is required foruse with the OM-CP-LF101A-KIT.The storage medium is non-volatilesolid state memory, providingmaximum data security even if thebattery becomes discharged. Thedevice can be started and stoppeddirectly from your computer and itssmall size allows it to fitalmost anywhere.
