- Provides calibrated, high-resolution (60 Hz signal and 1 Hz average) measurement of mechanically stimulated bioluminescence for assessing water column ecosystem dynamics.
- Field calibration light source is used to track sensor drift.
- Modular design for easy cleaning.
Bioluminescence, in conjunction with other IOPs, can provide a more complete picture of spatial and temporal variability of the biogeochemical complexity of coastal and ocean ecosystems, especially the response of the planktonic community, to environmental fluctuations.

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.
Do you want WET Labs to review your data?
In order for data questions to be answered in an efficient manner, WET Labs requests:
- The serial number of the instrument data in question. The most current calibration information
can be verified and the instrument settings upon delivery can be checked.
- Description of the deployment configuration. Questions to consider:
- What are the current instrument settings?
- What is the instrument orientation?
- Are there possible obstructions?
- Is it being used in a mooring, a profiler, or being towed?
- What were the deployment date and geographical location?
- How far into the deployment was the problem seen?
- What power supply and cabling are being used?
- What was the instrument condition during the last field service or retrieval?
- Do you have any pictures?
- Raw data files of the physical data in question
- examples of good raw data.
- examples of questionable raw data .
- Information about how the raw data was processed.
