Description
The Dua Export Instrumentation Sling Psychrometer, specifically the Dua-28 model featuring a wood body and a Centigrade (Celsius) scale, represents a reliable and versatile instrument for measuring relative humidity in various applications. This handheld psychrometer is equipped with two mercury-filled thermometers mounted on a rotating handle, allowing for on-the-spot and accurate humidity readings. Operating on the principle of evaporative cooling, the Dua-28 Sling Psychrometer is designed with one thermometer having a wet bulb covered with a moistened wick, while the other features a dry bulb. By swinging the instrument in the air, moisture evaporates from the wet bulb, causing a decrease in temperature. The temperature difference between the wet and dry bulbs is then utilized to calculate the relative humidity. The wood body of the Dua-28 model not only contributes to the instrument’s durability but also imparts a traditional aesthetic appeal. The Centigrade scale is ideal for users who prefer temperature measurements in Celsius units, catering to the international standard. This instrument finds practical applications in various fields such as meteorology, agriculture, and environmental monitoring. Its portable design makes it particularly convenient for obtaining precise measurements on location, facilitating the quick and accurate gathering of crucial data. Dua Export Instrumentation is renowned for producing high-quality precision instruments, and the Dua-28 Sling Psychrometer is a testament to this commitment. With its robust construction, dependable performance, and user-friendly design, this instrument proves indispensable for professionals requiring accurate humidity measurements in Celsius units. Whether used in laboratories or in the field, the Dua-28 Sling Psychrometer exemplifies Dua Export’s dedication to excellence in the realm of instrumentation.
