How do I protect my ECO from bio-fouling?

ECO instruments are designed for long term deployment capabilities with low power requirements, a large memory and an available Bio-wiper™. The Bio-wiper™ on the ECO was designed to protect the optical surface and has been very effective under most conditions.

If extra protection is required to prevent marine organisms from attaching to the instrument body near the optical head and interfering with the operation of the Bio-wiper™ we suggest using copper foil tape. The GoMOOS project developed a technique for their ECO sensors and WET Labs recommends this technique:

Apply electrical tape under the area where copper tape will be applied. This protects the meter from the significant adhesive residue of the copper foil tape.

Apply the copper tape to the prepped surfaces. There are different width copper foil tape options, with non-conductive adhesive, available from McMaster-Carr. NOTE: when applying the coper tape, the adhesive should not be touched. This will cause the tape to not stick to the electrical tape on the meter. When submerged in salt water, the copper will adhere more closely to the meter.

As long as the electrical tape is used, this technique does not violate the ECO warranty and WET Labs will service instruments that have had copper tape applied to them.

Important! Do NOT apply copper tape directly to the meter. Its adhesive is extremely difficult to remove. Meters returned to WET Labs wrapped in copper tape without the electrical tape preparation will have additional service charges applied.
