Kestrel 3500NV Pocket Weather Station with Night Vision – Your precise companion for demanding outdoor adventures
Imagine this: you're out and about in the Swiss Alps, dusk is falling, and suddenly the wind changes direction. The temperature drops, the humidity rises – experienced outdoor enthusiasts know that every piece of information counts now. This is where the Kestrel 3500NV Pocket Weather Meter comes in: your compact, high-precision weather data expert that provides you with all the crucial environmental conditions in seconds – even in complete darkness.
At Swiss-Sale.ch, we understand that you need to be able to rely on your equipment. That's why we offer the Kestrel 3500NV, a professional instrument developed and manufactured in the USA that meets the highest military standards. This weather meter is not just a measuring device – it's your strategic advantage in the great outdoors.
Kestrel 3500NV – 9 vital measurements – compact in the palm of your hand
The Kestrel 3500NV combines an impressive array of measurement functions in an ultra-lightweight device that fits easily into any jacket pocket. With just the push of a button, you get the following accurate real-time data:
Wind speed – Measure current, maximum, and average wind speeds in six different units (m/s, km/h, mph, ft/min, knots, or Beaufort scale). The patented, ultra-light impeller is mounted in gemstone bearings and guarantees maximum precision across a wide speed range – even in the slightest breeze.
Temperature – The external temperature sensor reacts instantly to temperature changes and reliably measures air, water, or snow temperature. For optimal results, simply wave the device in the air for 15 seconds – the sensor will then provide you with highly accurate readings in °C or °F.
Wind chill (perceived temperature) – How cold does the air really feel? This measurement is essential for all mountaineers, ski tourers, and winter adventurers to prevent hypothermia.
Relative humidity – The innovative, thermally compensated humidity sensor is specially designed for stability and accuracy during sudden weather changes. You can even recalibrate the sensor in the field with the Kestrel Relative Humidity Calibration Kit.
Heat Index – During intense outdoor activities in the summer, you'll know immediately when you need to take a break. This feature protects you from overheating and heat stroke.
Dew Point – Recognize when condensation begins – essential for photographers who want to protect their equipment or campers looking for dry accommodations.
Wet Bulb Temperature – The combination of temperature and humidity gives you a complete picture of thermal conditions.
Barometric air pressure – Monitor pressure changes and detect weather trends up to 3 hours in advance. Measures in hPa or inHg – perfect for weather forecasting in the mountains.
Altitude measurement – Precise altitude readings in meters or feet help you navigate and understand atmospheric changes.
Night Vision Backlight: Your invisible advantage in the dark
This is where the true innovation of the Kestrel 3500NV comes into play: the night vision-friendly backlight has been specially developed for military operations and outdoor professionals who need to preserve their natural night vision.
Scientifically proven: it takes 30 to 45 minutes for the human eye to fully adjust to darkness. A single flash of light in the white, yellow, green, or blue spectrum "bleaches" the rod cells in your retina and leads to temporary night blindness – the entire adjustment process starts all over again.
The Kestrel 3500NV elegantly solves this problem: the backlight appears in a soft gray-pink tone and uses an optical filter that reduces overall brightness and minimizes the harmful blue-green light spectrum. The light in the red spectrum prevents your photoreceptor cells from "bleaching" and protects you from night blindness and night vision fatigue.
In addition, the NV backlight is significantly dimmer than standard lighting, making you virtually undetectable to the naked eye during nighttime use. Whether you're hunting at night, hiking in the mountains, or conducting tactical operations, the 3500NV lets you maintain control of your surroundings without sacrificing your valuable night vision.
Note: The light appears gray-pink, not red, and is within the visible spectrum. It is therefore not compatible with night vision devices, but perfect for preserving natural human night vision.
Rugged, waterproof, and extremely durable—built for the toughest conditions
The Kestrel 3500NV is not a delicate laboratory instrument. It is a fully waterproof precision tool that floats if dropped in water and has passed all Mil-Spec drop tests. Whether you use it in pouring rain, drop it in a mountain stream, or use it in freezing temperatures, this device can handle it all.
The outer shell is made of fiberglass-reinforced plastic and provides first-class protection for the sensitive measuring components inside. Included in the scope of delivery is a robust, rubberized protective cover that protects the display and impeller, even when the device is thrown around in your backpack or equipment bag.
The compact design (12.2 x 4.3 x 1.5 cm) without the cover fits easily into any pocket. Weighing only a few grams, you'll hardly notice it – until you need it.
Simple operation, complex data – the intuitive menu system
Despite its wide range of measurement functions, the Kestrel 3500NV is very easy to use. The user-friendly menu system allows you to scroll through all 9 environmental measurements with just a few button presses. The large, backlit display shows you all the data clearly and concisely – even in direct sunlight or complete darkness.
The hold function freezes readings so you can take notes or analyze them at your leisure. Want to know how wind speed has changed over time? No problem—the device stores maximum and average values since it was turned on.
Important: The Kestrel 3500NV provides you with all current weather data, but does not store historical data series like the higher-end Kestrel 4000 models. For those who only need the latest weather information in real time, the 3500NV is the ideal choice.
Precise calibration and reliable measurement results
Each Kestrel 3500NV is fully assembled in the USA and carefully calibrated before shipping. Wind speed measurements are accurate to ±3%, and the humidity sensor can be recalibrated in the field if necessary.
Pro tips for optimal readings:
- Temperature: Hold the device in the wind or swing it back and forth for 15 seconds so that the sensor measures the air temperature and not the case temperature.
- Humidity: Move the device during measurement—airflow prevents moisture from your hand from distorting the result.
- Barometric pressure & altitude: These two values are interdependent. Ensure that your reference altitude or reference pressure is entered correctly (e.g., from a nearby airport or weather station).
- Acclimatization: When you take the device outside from an air-conditioned room or out of your warm pocket, wait 8-15 minutes for the device to adjust to the new environment.
Who is the Kestrel 3500NV the perfect choice for?
This high-precision weather meter is designed for anyone who deals with the elements professionally:
