Partech Portable Dissolved Oxygen Monitor

The Handy Polaris is the first Handy with the second generation Handy Probe and microprocessor controlled electronics. The Polaris benefits from advances in sensor performance and improved calibration accuracy whilst maintaining the ease of use of the Handy Beta.

Measuring Dissolved Oxygen in Activated Sludge Plants is a vital part of process control. The Polaris makes this an easy, fast and reliable process, allowing users to check process performance and the accuracy of any online instrumentation. The Polaris is also great for monitoring DO in Reservoirs, Rivers, Aquaculture and water treatment process.
