The Mk I & Mk II are portable (pocket sized) dissolved oxygen meters. The Mk II measures D.O. in both % saturation, ppm (mg/l) and temperature. The Mk I measures only D.O.. Calibration can be readily performed in the air. The meters are watertight and can be used in all kinds of weather.The galvanic cell probe stores dry. The meters require no warm up time and have a very short response time. They have strong membranes that are very simple to change when required.
