OxyGuard Cat No H01P2 Polaris Portable D.O. Meter and Probe


exc. GST

The Handy Polaris 2 hand-held meter makes it easy to measure dissolved oxygen and temperature.

The flat foil push buttons are easy to operate and the instrument is always ready to use – just press the “on” button and measure. Dissolved oxygen values are shown both in mg/l (ppm) and % saturation – the user chooses which parameter is shown in large figures.

The Polaris 2 has a memory that can contain 3000 complete sets of data – each with values of mg/l (ppm), % saturation, temperature, time and date. Values can be stored either automatically at preset time intervals, or manually. You can group values according to the place of measurement. Stored values can be transferred to a PC using the Polaris Link, which connects to the PC via a USB cable.

The datalogging and transfer capabilities, and other functions such as automatic calibration and self-check of the probe and meter, combine with the well-known accuracy, reliability and low maintenance needs of the OxyGuard Handy series to make an instrument that will serve you well for many years to come.
