The Kestrel 3500 Pocket Weather Meter is the required model for anyone wanting accurate supportive weather data and barometric readings.
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 Kestrel 3500 is switched off.
Wind chill and heat index are equivalent temperatures that show the user how their environment really feels. Wind chill is the combination of wind speed and temperature, while heat index is the combined effect of air temperature and relative humidity. 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. For those with requirements to operate in the dark, the Kestrel 3500NV (with an olive drab case) is available with a low intensity red backlight to preserve night vision.

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 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.
