PHYTOS 31
Leaf wetness sensor. Detect wetness and ice formation with a sensor that closely mimics the wetness state of real leaves.
The PHYTOS 31 lets you know leaf wetness in no uncertain terms. It measures both the onset and duration of wetness on a simulated leaf, which in turn predicts when the onset of certain diseases or infections may occur. It’s not only a more accurate instrument, it’s also the easiest to set up, making it a simple and straightforward solution to several problems.
- Accurate
- Easy to use
- Detect leaf wetness and ice formation
- Sensitivity without false positives
- Mimics a real leaf, so moisture will condense/evaporate as it would on a normal leaf
- Plug and play capability
- Use with the EM60G data logger for remote data collection
- No need to create thresholds when used with theEM60G data logger
- SDI-12 compatible
Detect Leaf Wetness and Ice Formation
Decagon's leaf wetness sensor is standardized, calibrated, and engineered to detect wetness (presence and duration) and ice formation straight out of the box. No user calibration needed.
Sensitivity without False Positives
Each sensor is accurately factory-calibrated to detect the smallest amounts of water and/or ice on the leaf surface. The sensor surface is coated in a non-hygroscopic layer, removing chances of false wetness detection.
Mimics a Real Leaf
The sensor's slim (0.65 mm) fiberglass construction closely estimates the total radiation balance of a standard leaf, so moisture will condense and evaporate from the sensor at a similar rate as it would on a normal leaf.
Plug and Read
Get to the data immediately with the Em50 data loggers. Just install the sensor, plug it into the Em50, set the clock and measurement intervals, and start recording data. No programming needed.
Want to Use a Different Logger? No Problem
Compatible with other data loggers (e.g. those manufactured by Campbell Scientific). Some programming is needed; however sample CSI programs are available on request.
Use the Leaf Wetness Sensor:
- To predict when to spray crops.
- To quantify water storage in the plant canopy.
- In studying and monitoring crops for foliar diseases including rust and blight.
