I have the Acurite unit in each cage and tub. The one's in the cages are fine since the snakes have the space to cruise around each night.
The one's in the tubs, however, get knocked into the water dish, get pee'd and poo'd on, and generally seem less reliable the longer I have them.
Since I have a laser temp gun, I use the Acurite to measure ambient temps and humidity.
Does anyone know of a reliable and sturdy hygrometer?
