This is a very simple yet important tool to monitor temperature and humidity. This unit can be mounted into the front of a cage or rack tub. You just need to cut a round 41mm hole with a circular hole saw. This allows for a beautiful inset display and the back of the reader will pick up the ambient temperature and humidity. Alternatively you can stick it on the back of the enclosure with double sided tap (making sure not to block the devices vents). It can also be fitted into a round cupboard vent which is commonly used for reptile enclosures.
