c-ROVER 2000

The c-Rover 2000 is an optical transmissometer designed for long-term deployment aboard profiling floats.

The c-Rover 2000 is an optical transmissometer designed for long-term deployment aboard profiling floats. Its 2000-meter rating meets the need to “park” a float at depth. The pressure housings are anodized aluminum, internally connected to the anode for optimal corrosion resistance, and provides enough volume to allow the instrument to be neutrally buoyant.

The c-Rover 2000 is optically and electronically comparable to the WET Labs C-Star. The C-Star is better suited for ship-based operations.

What should I use to lubricate bulkhead connectors?

WET Labs recommends keeping the connectors on your meter lubricated using a good quality silicone spray lubricant, such as 3M Silicone Spray or Loctite 8021 spray. These can be purchased at your local hardware store. Avoid silicone grease. It is messy and attracts contaminants. 

Do not use WD-40. It will destroy connectors.
