Optical Dissolved Oxygen Meter - Portable Optical DO Meter - 0.00-20.00 ppm - IP67 Waterproof

The Master Science Optical Dissolved Oxygen Meter is a hand-held meter that uses an optical DO sensor. It measures oxygen concentration from 0.00 to 20.00 ppm and saturation from 0 to 200%, with temperature from 0 to 50 °C.

The meter compensates automatically for temperature and barometric pressure and accepts a manual salinity factor. It runs on a rechargeable lithium battery in an IP67 housing, with a colour touch screen and storage for 1000 result sets.
