Using this Reptizoo thermo - hygrometer is easy. First, find a suitable spot in your terrarium away from direct heat or humidification sources.

If you notice any issues with the readings, check the placement to ensure it's not too close to heat or moisture sources. That's all you need to do to keep it working well for a long time.
