The Lucky Reptile Thermometer-Hygrometer PRO is both a thermometer and external humidity sensor.

This slim thermo-hygrometer has a combo sensor for measuring the temperature and humidity.

The device can be placed outside the vivarium, where it is protected from humidity and is easy to read, while the combo sensor is placed inside the vivarium.

A Min/Max-function is available to store the highest and lowest measured humidity and temperature values.
