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.
