The Portable optical DO meter makes use of the fast-response optical DO sensor RINKO, maintaining its high-speed response performance (99% response < 7sec at 25ºC). The meter probe is equipped with a temperature sensor close to the sensing foil, and the measurements are made by simply inserting the probe into a BOD (Biological Oxygen Demand) bottle (the calibration is carried out using the National Metrology Institute of Japan (NMIJ) certified traceable gases standards). Differently from galvanic electrode sensors, the instrument does not require water sample stirring or fixing reagents, since there is no oxygen consumption. Thus, the required time to estimate dissolved oxygen is considerably reduced. The display unit shows the output instantaneously, and you can check the measured values in real time
