Leaf wetness-Simplified
Diseases and infections can destroy an entire crop, but applying
fungicides is costly and time-consuming. If you're deciding when to
spray by monitoring leaf wetness with a resistance grid sensor,
you'll have trouble accurately determining wetness duration without
a lot of extra work. You need an accurate sensor that is simple to
set up with stable, consistent, easy-to-use thresholds like the
PHYTOS 31.
Say goodbye to guesswork
The PHYTOS 31 accurately 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, but it's also the easiest to set up, and when
paired with the ZL6 data logger, it gives you access to remote data
in real time, making it a smart, simple and straightforward sensing
solution.
Accuracy you can feel secure about
Only the PHYTOS 31 ensures that every water droplet is measured.
Unlike conventional leaf wetness sensors, its resistance grid
doesn't use salt-laced latex paint which absorbs water. This gives
it extra sensitivity to avoid false positives. So there's no having
to cull data to figure out if the sensor was really wet or not.
Simply accurate
Through sophisticated, yet simple engineering, PHYTOS 31
delivers unmatched accuracy in an easy-to-use sensor. It saves you
both time and labor, while reducing your worry and guesswork.
Even detects ice formation
The PHYTOS 31 uses capacitance technology, so it can sense
sub-milligram levels of water condensing on the surface, including
frost and ice formation. That way you can establish a threshold
that not only indicates when the sensor is wet, but also senses how
much water there is. This kind of moisture clarity reduces
guesswork and worry about accurately predicting disease
conditions.
Simple as nature
When your moisture sensor mimics the energetics of an actual
leaf, making measurements is a lot easier. There's no having to
paint your sensor's non-resistance grid first to get good data. No
creating thresholds. And no worrying about lots of wiring. Instead,
all you have to do is plug the PHYTOS 31 into the ZL6 data logger,
where wet and dry threshold ranges are already programmed in. The
result: you save time.
The problem with most water depth, temperature, and electrical
conductivity sensors (CTD sensors) is that their cost is
prohibitively high. Plus they often require an extra barometric
pressure sensor to correct for atmospheric pressure. You need a
low-cost water level sensor equipped with everything necessary for
things like tracking changes in solute movement, groundwater
recharge, and surface water hydrology. You need HYDROS 21.
