Overview
The Onset MX2500 Anti-Fouling Copper Guard can be used in addition to the standard electrode guard for protection against biofouling during deployment. The anti-biofouling guard uses copper to reduce biofouling, while still allowing proper water flow to the sensor.
Maintenance
Copper protects the logger by interacting with the chemistry of the water in which it is deployed. This reaction is an oxidation-reduction reaction that produces a patina. The patina depends on what specific chemistry is present, as well as depth, temperature, etc. The patina should not affect the ability of the guard to protect the logger; however, if the logger is conspicuously gaining more fouling, it may be time to replace the guard. The guards' ability to protect the logger relies on the copper getting consumed.

NexSens X3 Data Logger Review
Extreme environments meet extreme design with the NexSens X3 Data Logger . The new logger offers the latest in real-time monitoring technology with wireless communication, a large plug-and-play sensor library and ultra-low power consumption, all in a waterproof marine-grade housing. 
 
 The X3 is built to handle harsh weather, floods, high winds and rough seas, and it stands alone; no additional protective housing needed. With an operating temperature that ranges from -40°C to 70°C, the logger can withstand arctic environments and extreme heat. 
 
 
 
 A conformal coating on the internal circuit board isolates it from moisture and humidity.

When Kentucky’s Emergency Response Team (ERT) has to act quickly in response to chemical and oil spills in the Commonwealth, they rely on small, easily deployable buoys to collect critical data that help minimize and evaluate damages in environmental emergencies. 
 
With a background in geology, Robert Blair primarily worked with groundwater and got involved sporadically with the ERT during groundwater contamination emergencies. Over time, this involvement led to him joining the ERT as an On-Scene Coordinator and then becoming the branch manager for the team and overall Emergency Response Branch .
