Copper is widely recognized as an effective inhibitor to biological growth and it has been used successfully in many applications where biological activity impedes the desired result. One example is in marine transportation where ship hulls are often treated with copper to be kept free of biological growth that slows the ship’s speed.
In natural aqueous environments, copper ions are released from its solid form and become available to microorganisms in sufficient concentrations to be toxic. This is the primary reason copper is such an effective tool for use against biological growth.
Specific to applications in water quality monitoring, instrument manufacturers and their users have been using copper to prevent biological growth from negatively impacting measurements. Experiments and user experience clearly show that copper effectively inhibits biological growth in many aqueous environments. Comparing biological growth rates on untreated surfaces to surfaces that are covered with some form of copper show that biological growth is reduced.
Copper Sensor Guard
Available for multiparametersondes, copper sensor guards are identical to standard sensor guards, only constructed out of a copper alloy. Copper sensors guards inhibit the growth of matter that would normally adhere to the sensor guard and potentially interfere with measurements.
Available in 2” and 3” widths, copper tape offers the flexibility and protection of individually wrapping each sensor.
Copper mesh can be applied to either a standard or copper sensor guard and reduces the likelihood of matter entering and building up on sensors without creating a substrate for organisms to attach.
