The Kestrel 3500 T Weather Meter takes all the great features of the Kestrel 3500 and adds in one additional reading, Delts T. The Delta T is 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 reccomended to apply pesticides when Delta T is above 10 - a range of 2 to 8 is ideal. With the Kestrel 3500 T, the calculation is done for you, accuratly and simply.
