The Handy Polaris hand-held meter makes it easy to measure dissolved oxygen and temperature. The flat foil pushbuttons 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 – you can choose which parameter is shown in large figures. Measurements are compensated for changes in barometric pressure. 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.
