Dissolved Oxygen Electrode

Any analog or digital pH meter can be used as the readout for BOD measurements. Measurement range is from 0 to 14 ppm. Accuracy is ±0.05 ppm or 2% of reading, whichever is greater between 15 and 35°C. Time for 96% response is less than 30 seconds. For standardizing, unit uses room air. Electrode unit includes replaceable membrane/electrolyte module, electronic circuits, and thermocompensator. An accessory overflow funnel with built-in stirring bar for measuring of oxygen in BOD bottles is supplied. Unit operates on two Mallory type 10L14 batteries or equivalent. Has 75 cm cable and BNC connector. Batteries and instruction manual are included. Warranty: 24 months.
