Compact and reliable, it’s perfect for classrooms, labs, and environmental monitoring, delivering precise readings within a 120°F range. ## Description 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. Review: wet/dry bulb - Excellent for tracking humidity in the house summer and winter. Quite accurate - checked both bulbs in ice water that had stabilized at 32F. Both reading were spot on 32F. My last one (dropped it and broke) was off about 2F on the wet bulb. I managed to move the glass - checked it again - then put a drop of superglue on one of the hold downs. It is not super lab quality (I'm a chemist), but for the $23 it is a very good instrument. Review: Junk - DO NOT PURCHASE. IT IS NOT RETURNABLE IF DEFECTIVE!!! The two thermometers do not read the same temperature when both are dry. One reads 65f the other 100f. TOTAL RIP OFF. DO NOT PURCHASE> ## Features - 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. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07SLC169Q | | Battery Description | No batteries needed | | Best Sellers Rank | #295,705 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #474 in Weather Thermometers | | Brand Name | EISCO | | Customer Reviews | 3.6 3.6 out of 5 stars (24) | | Item Dimensions W x H | 3"W x 11.5"H | | Item Weight | 4.8 ounces | | Manufacturer | Eisco | | Mounting Type | Wall Mount | | Temperature Accuracy | 1 | | UPC | 849230038021 | | Upper Temperature Range | 120 Degrees Fahrenheit | ## Product Details - **Battery Description:** No batteries needed - **Brand:** EISCO - **Item Weight:** 4.8 ounces - **Mounting Type:** Wall Mount - **Product Dimensions:** 3"W x 11.5"H ## Images ![EISCO Wet-Dry Bulb Hygrometer, Wall Mounted Thermometers - Image 1](https://m.media-amazon.com/images/I/710uSDxXL7L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ wet/dry bulb *by J***D on May 27, 2021* Excellent for tracking humidity in the house summer and winter.
