This humidity gauge is a metal sheet with a glass gauge with bulb on the front, and a glass water reservoir fixed at the back. A cotton wick passes from the reservoir to a piece of cloth tied round the bulb of the gauge. There are two hooks for hanging the gauge. This gauge was used at a small farm (Staddlestones, in Headley) to ensure that the humidity in the poultry incubator was correct.
