These mounts are designed to easily install a hygrometer/thermometer on the inside of transparent container. The mount consists of two plates. The outer plate can be attached to the respective container with double-sided adhesive tape or glue. This removes the need for drilling holes in the container and using additional fasteners.
The hygrometer clips into the inner mounting plate and than both are clipped into the outer mounting plate. This allows for the hygrometer to be easily removed later for battery change or replacement.
