I have one of these measuring my temps/humidity but I have stumbled upon an issue. Does anyone know where the sensor is for the hygrometer? Is it in the probe or is it in the display portion? My device is reading a humidity of 84% and I've had fans blowing in the vents all day long and the lowest it got down to was around 70%. I was wondering if perhaps it is much dryer in the enclosure than I originally thought and the humidity sensor is on the display box somewhere and reading ambient levels outside the enclosure (the display is outside the tank with a separate thermometer measuring the cool end)?

Also, I have my probe adhered to the bottom surface of the enclosure. Should I pull it up and just lay it on top of the substrate (cypress mulch)?
