The Kestrel 5500 is a rugged, handheld weather meter designed for professional use and field applications, offering 14 environmental measurements including wind speed, temperature, humidity, barometric pressure, dew point, density altitude, wind chill, and more. It features onboard data logging with up to 10,000+ time‑stamped data points and graphing capability so you can view trends directly on the device. The meter has a high‑contrast, sunlight-readable LCD with dual‑color backlight (white/red) for day or night use. Built to survive tough environments, it's drop-tested to MIL‑STD‑810G, waterproof to IP67, and even floats if dropped in water. It’s powered by a single AA battery and provides durable operation in remote locations. The impeller (wind sensor) is user-replaceable and mounted on a jewel bearing to ensure high sensitivity and long life. With optional LiNK Bluetooth connectivity, you can sync data to iOS/Android devices, while a rotating vane mount lets you convert it into a portable weather station. The device also offers a digital compass, adjustable data‑logging interval, and min/max/average measurements.
