DUAL THERMOMETER DESIGN || Features two identical thermometers, one with a dry bulb and one with a wet bulb, for accurate relative humidity measurement.
MEASURES HUMIDITY & WATER VAPOR || Helps determine the water vapor content in the air by comparing the temperature difference between the dry and wet bulbs.
WALL-MOUNTED DESIGN || Compact and convenient for home, school, or laboratory use. Measures 11.5" long, 3" wide, and 0.5" thick.
EVAPORATION-BASED COOLING || As water evaporates from the wet bulb, it cools the thermometer, allowing for precise humidity readings when exposed to airflow.
IDEAL FOR CLASSROOM & LAB USE || Perfect for educational demonstrations in physics, environmental science, and meteorology studies.
The Eisco wet-dry bulb hygrometer is a wall-mounted device designed to measure relative humidity and water vapor content in the air. It consists of two identical thermometers, one with a dry bulb and one with a wet bulb, to determine humidity levels by comparing temperature differences. When exposed to airflow, water from the wet bulb wick evaporates, cooling the thermometer. The drier the air, the greater the temperature difference between the two thermometers. This device is an excellent tool for classroom demonstrations, laboratory experiments, and environmental studies.
