Humidity is important for keeping your reptile or amphibian healthy and most shedding problems with reptiles are linked to incorrect humidity levels.
Using a habistat hygrometer will help you maintain a healthy humidity level for your pet with its large easy to read display.
Hygrometers easily install inside your vivarium or terrarium (analogue readers like this one need to be placed inside where you want to measure the conditions), they will still work in humid environments due to their fog resistant seal.
No batteries or external power is required, simply stick inside your enclosure with the sticky back pad included.
Position the hygrometer halfway between the hot and cold end to give an average reading.
