OxyGuard Polaris C DO Meter

Type: 10' cable


The Polaris C meter is a high-performance, low-cost and almost maintenance-free meter for measuring dissolved oxygen and temperature. The meter is sturdy, easy to use and has an extensive longevity making it ideal for harsh conditions.
Polaris C can store up to 2500 complete data sets, including time and date stamps. The logged data is stored in the meter or can be transferred to Cobália using Bluetooth.
Scan the Cobália NFC tag of the tank and all data will be uploaded to your “digital farm”. Tank specific data assigned to the tags will be stored in Cobália for analyses on temporal variations, multivariable analyses on performance and for the generation of graphs.
The meter has a built-in self-check of all hardware, automatic barometric pressure compensation and a notably short response time. With this meter, you get the high-quality associated with OxyGuard technology and a product that will serve you well for many years.

We can customize these meters to suit your needs with longer cables or reels please call for a quote.
