Measurement ranges: Temperature: from 0 to +25 °C. Humidity: from 20% to 90%. The VIT-1 hygrometer consists of a plastic base with a temperature scale and two capillaries. One of the capillaries is moistened by a fabric wick placed in a water reservoir. A table is included for determining relative air humidity based on the difference between the "dry" and "wet" thermometer readings.
