Disclosed is a wick for a wet bulb, wherein the bulb is elongated with a free end and a supported end. An absorbent fabric has a portion configured as a folded over sleeve to at least partially closely surround the bulb. The sleeve has two ends, one of which is open and the other of which is closed to permit the open end of the sleeve to be slipped over the free end of the bulb and passed to the supported end until the closed end of the sleeve approaches the free end of the bulb. A plastic film lining inside the sleeve is resistant to corrosive materials to protect the bulb from corrosive materials and has a lower coefficient of friction than the fabric to ease installation over the bulb. A tail contacts a water supply to pick up water and transport it to the sleeve to wet the bulb.
