Mason's Hygrometer with Red Liquid

Sper Scientific 736740 Mason's Hygrometer with Red Liquid: Precision Humidity Measurement

The Sper Scientific 736740 Mason's Hygrometer offers a reliable and classic method for accurately measuring relative humidity. This essential instrument utilizes the proven wet-bulb/dry-bulb psychrometer principle, known for its precision in various environments.

How It Works: The hygrometer features two thermometers mounted side-by-side. One, the "dry-bulb" thermometer, measures the ambient air temperature. The second, the "wet-bulb" thermometer, has its bulb encased in a wick that is continuously kept moist by a siphon leading to a water reservoir. As water evaporates from the wet-bulb, it cools, and the temperature difference between the wet and dry bulbs is directly related to the relative humidity of the air.

Key Features:

• Safe Red Liquid: Unlike traditional mercury thermometers, this model employs a vibrant red liquid, ensuring easy readability and eliminating the hazards associated with mercury, making it safer for a wider range of applications.
• Dual Scale Readings: The thermometers provide clear measurements with dual scales, covering a range of -10°C to 50°C and 10°F to 120°F, accommodating various climate and scientific needs.
• Included Humidity Chart: An easy-to-use conversion chart is provided, allowing you to quickly and accurately determine the relative humidity by comparing the wet and dry bulb temperature readings.
• Durable Design: Built for longevity and consistent performance, ideal for laboratories, greenhouses, industrial settings, environmental monitoring, or educational purposes.

The Sper Scientific 736740 Mason's Hygrometer is an indispensable tool for anyone requiring accurate and straightforward humidity assessment, offering a blend of traditional reliability and modern safety.
