Brass Effect 70 mm Dial incubator Hygrometer

A small brass effect unit that fits in neatly into any incubator to give a very accurate humidity reading.
Made from plastic, easy to read with large clear numbers and dial.
Unlike the digital hygrometer this isn't given to spikes if a droplet of water settles on the sensor and gives a reliable reading at all times.
Brilliant spot on humidity reading for: incubators, hatchers, brooders & brooder rooms and wine cellers too!
