Polaris C meters are portable instruments designed for fast and accurate spot measurements of environmental
parameters in aquaculture, research and industrial use.
Polaris C Salinity measures salinity, conductivity and temperature in water. It provides a quick and reliable check of salt
levels to help maintain stable conditions for fish health and system balance. The meter is factory-calibrated to the PSS-78
standard and requires no user calibration.
