Genuine replacement humidity sensor probe for the Willhi humidity controller. If your humidistat is reading incorrectly or not switching on and off properly, a fresh sensor probe is usually the fix.
⚠ Important — Check Your Model Before Ordering
Due to a global chip shortage, older humidistat sensors are no longer available and will not work correctly with new models.
If your humidistat has two small indicator lights under the LED labeled ‘work’ and ‘set’, we are not able to replace your sensor.
Please check the product images to confirm whether your sensor is the old or new style before ordering. Questions about an older humidistat? Email John@thehouseofhydro.com before ordering.
