Exo Terra Nano USB Repti Humidifier PT2446 – Replacement Incubator Part

The ET Nano USB Repti Humidifier (PT2446) is a replacement humidifier unit designed for use with the Exo Terra Precision Incubator Pro with humidity control. If your original humidifier has failed or been damaged, this is the direct replacement to restore accurate humidity regulation during incubation — without replacing the entire unit.

Compatibility

This humidifier connects via USB to the dedicated port located at the rear of the Precision Incubator Pro's LED display panel, positioned alongside the main power cable. It is designed specifically for this incubator and is not a universal humidifier.

Installation

The unit sits within the designated opening in the foam insert inside the incubator. Fitting is straightforward and requires no tools — connect the USB lead, position the humidifier in the foam recess, and it is ready to prime.

Priming the Humidifier

• Pour a small amount of water into the centre of the device
• Invert the unit and shake gently to remove any excess water
• Place the humidifier flat on the water surface so it floats — humidification begins automatically from this position

Keeping a working humidifier in your incubator is essential for maintaining stable humidity levels throughout the incubation period. Having a genuine replacement on hand means any interruption to your incubation setup is kept to a minimum.
