Here’s the one that started it all! Measuring wind is a breeze with the Kestrel 1000. We developed the Kestrel 1000 Pocket Wind Meter in 1995 when NK’s co-founder, Richard Kellerman, needed a reliable wind meter for flying his glider. Over 15 years later, it looks a little slicker, and it gives you the wind information you can count on with a simple, reliable and accurate pocket wind meter. The Kestrel 1000 can easily be switched between mph, km/h, ft/min, m/s, knots and Beaufort.
The Dickson TH8P3 is a portable device which automatically records the air temperature (-20-120°F) and humidity (0-110%) 24-hours/day, seven days per week, providing a permanent record, even when you can't be on-site.
The US Weather Bureau Psychrometric Tables are used for determining the relative humidity and dew point temperature from the dry and wet bulb temperature readings on sling or battery-powered psychrometers. The tables cover the range of 23.0 to 30.0 inches barometric pressure.
