The humidity gauge allows you to quickly and easily check temperature and humidity le vels in your cooler to ensure your hibernating Mason bee cocoons are stored at the right humidity level. Place the humidity gauge inside your HumidiBee to make sure the humidity level surrounding your cocoons is above 30%. Batteries included. Product instructions Show more
