Kestrel 3500DT pocket weather meter - 0835DT

The Kestrel 3500 Delta T Pocket Weather Meter is a small, pocket-sized electronic rotating vane type of anemometer with built-in temperature, humidity and barometric pressure sensors. It uses high precision jewel bearings and a light weight impeller to provide accurate air flow measurements even at low speeds. The impeller assembly is replaceable by the user in the case of damage.

This specialist weather meter, for those in the agricultural industry involved in crop spraying, includes the measurement of Delta T. 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 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.

By also measuring other critical conditions, such as relative humidity and wind speed, the kestrel 3500 delta T helps ensure safe and effective spraying.

A trend arrow displays whether the pressure is rising, stable or falling, this trend is calculated over a 3-hour period. The pressure is monitored even when the 3500 Delta T is switched off.

The humidity sensor compensates for temperature changes and is designed for stability and accuracy.

The liquid crystal display has large 9mm high digits and is backlit for a clear readout in low light conditions. Power is from an easily replaceable standard lithium coin type cell, which will typically give up to 300 hours of operation. The instrument automatically switches off if no keys are pressed for 45 minutes.

The Kestrel 3500 Delta T Pocket Weather Meter is made from high impact injection moulded plastic and corrosion resistant materials with the electronics fully sealed. It will float if accidentally dropped into water. There is a hard cover for protection when not in use and a lanyard is provided for added security.
