OxyGuard Handy Polaris 2

WMT, the USA distributor for OxyGuard, is pleased to introduce the new Handy Polaris 2, Portable DO Meter with data-logging and data-transfer capability.

The Handy Polaris 2 is a hand-held, battery-powered dissolved oxygen (DO) Meter. Polaris measures mg/1 (ppm), % saturation, temperature (°C or °F), has manual salinity compensation and automatic compensation for temperature and barometric pressure.

Just as with the original Handy Polaris 1, the Handy Polaris 2 can be switched on and put in the water to measure, but measurements made with the Polaris 2 are supported by a range of advanced functions designed to make things even easier for you.


  • Large Display
  • Automatic Calibration
  • Choice of Language and Units of Measure
  • Multi-Parameter
  • Automatic Self-check and probe-check
  • Barometric Pressure Compensation
  • Automatic or Manual Data Logging
  • Data Grouping according to tank, pond, or cage
  • Data Transfer with Link
