EZO™ Humidity Circuit

The EZO Humidity Circuit is designed to be embedded with your electronics, reading the humidity of your enclosure. While there is no reason it can’t read the humidity of a room, it lacks the housing needed to protect the electronics. The EZO Humidity circuit gives the same readings as our EZO-HUM Probe. There is no difference in the readings or accuracy, only the design.
