Measure Humidity with Ease: Our Sling Psychrometer Kit is a straightforward tool used to measure the moisture content in the air. By comparing temperatures from two thermometers, students can accurately determine relative humidity and dew point. Wet and Dry Bulb Thermometers: The kit includes both a wet bulb and a dry bulb thermometer, which give different temperature readings when spun. This temperature difference is then used to calculate humidity levels, providing a hands-on learning experience. Durable Design and Temperature Range: Each thermometer is made with a metal backing and measures a broad temperature range from -20 to 110°C, making it suitable for diverse weather conditions and laboratory experiments. Complete with Wooden Handle and Instructions: The psychrometer is equipped with a sturdy wooden handle for easy spinning. Instructions are included, helping students understand the step-by-step process of using the psychrometer and interpreting the results. Includes instructions GSC's products are useful in a traditional classroom setting or homeschool. Our Sling Psychrometer Kit is a simple hygrometer used in measuring the moisture content in the air. When spun around on their wooden handle, the wet bulb thermometer and the dry bulb thermometer will read different temperatures. This information can then be used to determine relative humidity and dew point. Instructions included.
