Antique device to measure relative humidity with wet. I believe humidity is found by adjusting index pointer to corresponding temp on thermometers and reading scale where index arm swings (something like that). Brass finish, frame & hardware, engraved german silver scale, full instructions printed on rear. Complete with no missing parts, fantastic condition with no damage. Dry thermometer working correctly, water tank for wet thermometer doubles as the base (see fill cap). Wet thermometer not tested but should work fine. Instrument measures 10-1/2″ x 8″ x 3, box missing the wood lid. The item “Antique 1902 Tycos Lloyd’s Hygrodeik Hygrometer Taylor Scientific Instrument Co” is in sale since Monday, January 20, 2014.

We are pleased to offer this exceptionally well preserved. Lloyd’s hygrodeik by tycos, rochester. Made in the early 20th century, for andrew j. A hygrodeik measures relative humidity, with wet and dry thermometers, and an index arm indicating relative humidity on the scale.

Condition: this piece is in excellent, all original, with no damage (other than the finish wear and patina) and a small ding on the rear of the base. A partial piece of the wet side wick is still attached to the bulb.

The water container is perfect, and appears to have a ground edge on the top. The instructions on the back are extremely clear and easy to read. The front scale is dirty, but could be cleaned for a much better display if desired.
