Hang On Aquarium Thermometer 12mm
A neat little thermometer that is a little different to most in so much as it just hangs onto the side of your aqaurium. This makes it a lot more subtle as there are no unsightly suction cups that get in the way.
The crystal glass is easy to read with blue solution. Temperature from 0-40C.
This particular model is suitable for glass widths of up to 12mm.
