This digital humidistat will control the Hydrofogger, Minifogger, or either of the Cuoghi humidifiers. It offers adjustable range from 30 to 90% rH, with accuracy of +/- 5%. No wiring necessary-simply plug this humidistat into a standard GFCI outlet and then plug the humidifier into the humidistat. Dial your desired humidity level on the digital screen and the humidistat will turn the fogger on/off in order to maintain the setpoint you have chosen. However, use of a hygrometer in to measure the accuracy of the humidistat is strongly recommended.
