## Overview

The EISCO Wet-Dry Bulb Hygrometer is a wall-mounted dual thermometer device that measures relative humidity by comparing temperatures of a dry and a wet bulb. Its evaporation-based cooling method provides accurate water vapor readings without batteries, making it perfect for educational, laboratory, and home use.

## 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>
