The Polaris C LDO Optical Handy is an almost maintenance free meter for measuring dissolved oxygen and temperature. The Handy is sturdy, easy to use and has an extensive longevity making it ideal for harsh conditions.
Polaris C LDO can store up to 2500 complete set of data, including time and date stamps. The logged data can be stored either manually or automatically with the possibility to group the data into categories.
The stored data can be uploaded directly to Cobália using Bluetooth technology. Scan the Cobália NFC tag on 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 analysis on temporal variation, generation of graphs and for multivariable analysis on performance.
The meter has a built-in self-check of all hardware, it compensates automatically for barometric pressure and it has 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.
