Pro-Oceanus Systems M220 Mini CO2 Digital Loggers

Procurement Summary

The GLERL requires a Mini CO2 Digital Logger that will document the impacts or potential shifts in phytoplankton species in the Great Lakes. The M220 Mini CO2 Digital Logger uses infrared detection to measure the partial pressure of CO2 gas dissolved in liquids with a range from 0-1000 ppm up to 0-100%. The instrument is a compact, lightweight, plug and play sensor; and measures total dissolved gas pressure (TDGP). The housing is rated to 6000 dbar of hydrostatic pressure, and is resistant to most corrosive liquids. The M220 Mini CO2 Digital Logger includes the following components/specifications and is the only known product capable of meeting the needs of the GLERL. The GLERL is a multidisciplinary environmental research laboratory that provides scientific understanding to inform the use and management of Great Lakes and coastal marine environments. The GLERL uses sensors to collect and monitor the CO2 and acidification levels of the Great Lakes and provide data for HAB analysis. As atmospheric CO2 increases, the availability of dissolved inorganic carbon (DIC) is shifting within aquatic systems causing the pH to drop. The GLERL requires the M22 Mini CO2 Digital Logger in order to document the impacts or potential shifts in phytoplankton species composition and abundance.
