Minimise waste and maximise safety with the Kestrel 3500 Delta T. Delta T allows you to accurately assess acceptable spraying conditions to ensure you're within guidelines and help you select the right spray nozzle.

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.

The Kestrel 3500 DT incorporates a Delta T calculation, the spread between the wet bulb temperature and the dry bulb temperature (in degrees C or F). 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.

Every Kestrel is individually calibrated to NIST-traceable standards and comes with a free Certificate of Conformity (Individual NIST certificates and recalibration are also available.)

If your application demands regular calibration, simply pop in a new impeller and the Kestrel air velocity meter is restored to like-new factory calibration standards.
