This unit is simply two temperature thermostats on one box. It is perfect for controlling two heaters independently. When a specific temperature gradient is required this is the unit to use. It will control two heaters with a maximum of 300 watts for each channel. This enables each heater to be set at a different temperature , even in the same terrarium. One channel can control the general background heat, whilst the other channel can control a "hot spot" to give the reptiles that essential temperature gradient that is so important to their husbandry. It can alternatively be used to control two seperate heaters in two seperate cages.
In order to sucessfully keep reptiles in captivity you need to provide the correct thermal gradient for the species kept, in order for it to thrive. Without a thermostat you have no control over the thermal gradient within your vivarium which will fluctuate with the ambient temparature, depending on the time of year.
We therfore always recommend the use of thermostats.
