Copper is a potent, naturally occurring biocide; toxic to both invertebrates and bacteria. Using a copper anti-fouling screen effectively reduces the amount of biological material that builds upon the probe. The Anti-Fouling screen lasts ~ 6 months in seawater and ~one year in freshwater. This product fits all standard 12mm probes. See the spec sheet to ensure compatibility with your probe.

There’s a ton of different ways to read water level. Pressure sensors give you high accuracy; ultrasonic sensors are contact-free but, the simplicity and low cost of a float switch can’t be beat. Sure, there are a lot of crappy float switches out there, but don’t worry; over the years, we found the ones that work. We use these float switches all the time in our own lab, and we thought you might like them as well.
