Polaris C meters are portable instruments designed for fast and accurate spot measurements of environmental
parameters in aquaculture, research and industrial use.
Polaris C Atmosphere measures oxygen concentration in gas (% vol) along with temperature and barometric pressure.
Ideal for monitoring ambient air, checking gas purity or verifying oxygen levels in controlled environments.
