To ensure safety and effectiveness when spraying, it is critical
to measure relative humidity, wind speed and wind direction. Many
locales regulate the maximum permitted wind speed during spraying to
minimize spray drift. In hot, dry conditions, expensive chemicals
may evaporate into the air rather than onto your crops. However, you
can minimize costly evaporation by selecting an appropriate nozzle
and increasing the spray droplet size.
Quickly & Accurately Calculates Delta T For You
The Kestrel 3500 DT incorporates a Delta T calculation, the
spread between the wet bulb temperature and the dry bulb temperature
(in degrees C). Delta T offers a quick guide to determining
acceptable spraying conditions. For example, it is not recommended
to apply pesticides when Delta T is above 10 — a range of 2 to 8 is
ideal. With the Kestrel 3500 Delta T, the calculation is done for
you accurately and simply.
The Kestrel 3500 Delta T incorporates barometric pressure
correction in its wet bulb temperature calculation, ensuring
accuracy even on low pressure days, at high altitudes, and in very
dry weather when Delta T monitoring is important. No other pocket
weather meter offers this feature with this level of accuracy.
