The Exo Terra Digital Hygrometer is equipped with a remote sensor for accurate measurement and durability.

These precision instruments come with a programmable minimum and maximum memory setting which can be controlled with one single button.

The sensor is held in place with a suction cup, while the instrument can be mounted in three ways - with Velcro (included), with a screw or it simply slides into place on a new Exo Terra Compact Top or Dual Top.
