Feel relaxed monitoring your colony's temperature and humidity levels with these accurate Hygrometers. Perfect for ensuring your setup isn't too dry or too humid. Just place the probe in the area you want to read.
Please note these hygrometers are not built to be in very humid conditions for extended periods of time (85%+) as the probe will likely become waterlogged.
