This is a great unit to retro-fit almost any model of incubator and due to its small size it is easy to drill a hole to fit and also easy to find a mounting position on most incubators.

Also included is a rubber mounting ring to help with providing a snug fit and tidy installation.

This, the dial version is great if you are getting false readings from digital sensor models. Digital hygrometers are great for most model incubators, but they are known to provide false readings if the air within the incubator is forced at a higher level (for example, having a powerful fan in a very small incubator),in these situations, this unit is then a better choice.

Specification: This is a small hygrometer and is only 37mm making it easier for drilling an installation hole.
