Handy Polaris 2 Portable Dissolved Oxygen Monitor
Portable Dissolved Oxygen Monitor
Measuring Dissolved Oxygen in Activated Sludge Plants is a vital part of process control, the Polaris 2 makes this an easy, fast and reliable process, allowing users to check process performance and the accuracy of any online instrumentation. The Polaris 2 is also great for monitoring DO in Reservoirs, Rivers, Aquaculture and water treatment process.
The handheld monitor has a large display and an extremely long battery life – many months of normal operation. The system carries out a self-check process every time it is switched on and will carry out calibration of the system at the push of a button. The long standing ability to store the probe dry removes that need for regular probe regeneration and means that the system is ready for use straight from the bag.
The Handy Polaris 2 includes an in built data logger that can store up to 3000 data sets (Dissolved Oxygen, Temp, Date/Time) that can be easily uploaded to the PC via the USB link cable
The Handy Polaris 2 is supplied with a self polarising, galvanic sensor which is self temperature compensating which can be stored dry. There is no need for any maintenance other than wiping the sensor clean after use. The power consumption is exceptionally low, typically providing 1400 hour use from a single 9V battery.
The Handy Polaris 2 comes complete with membrane maintenance kit, USB to PC link cable and carry bag as standard
