The Kestrel 3500 is the most powerful of the Kestrel 3000 series, measuring temperature, wind speeds, barometric phenomena and pressure trends for up to 3 hours or even longer if needed. The Kestrel 3500 is perfect for the user who needs important weather data, but who doesn’t require the ability to store the numbers for review at a later time. The Kestrel 3500 handheld meter was designed with the same simplicity of the Kestrel 1000 in mind, but with the ability to do much more advanced tasks included in its design.
The Kestrel 3500 NV, with night-vision preserving backlight, was launched in 2005 in response to military personnel and pilot’s requests for a handheld meter that would help them to sustain natural night vision when using it. The Kestrel 3500 NV’s backlight are much dimmer than the lights found in most electronic devices, making it difficult to see with the naked eye during nighttime operations. The backlight uses an optical filter to reduce brightness and minimize the blue and green spectrum light. By utilizing this type of backlight technology, the Kestrel 3500 NV is the best choice for preserving night vision.
Both the Kestrel 3500 and the Kestrel 3500 NV come with a slip-on protective cover, a handy neck lanyard and a Kestrel Certificate of Conformity. Each meter also comes with a CR2032 coin cell battery with an average life of 300 hours.
