MA845 Polarographic Dissolved Oxygen Probe
MA845 is a polarographic replacement probe for the MW190 MAX Dissolved Oxygen Bench Meter.
The refillable polarographic probe has an oxygen-permeable polytetrafluroethylene (PTFE) membrane sensor for measuring dissolved oxygen (DO) levels in aqueous solutions.
The probe uses a platinum cathode and a silver chloride anode which the MW190 MAX meter polarizes so that oxygen passing through the membrane can be measured to produce stable, accurate readings.
