The OxyGuard Handy Polaris 2 s a portable D.O. meter that also measures % saturation, mg/L (ppm), temperature and has salinity compensation. Measurements are compensated for temperature and barometric pressure. The probe is galvanic type and fully field-serviceable. Has a large display with backlight and offers automatic calibration and a choice of language and units of measurement.
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.
