Milwaukee MA845 Polarographic Dissolved Oxygen Probe

The Milwaukee 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.Design Features:Reinforced plastic body for durability.Built in temperature sensor to achieve thermal equilibrium between the sensor and the sample for more accurate reading.10 inches long with a tip that tapers from 1-1/2" to 3/4" in diameter.6.5 (2 meter) foot cable with a 7-pin DIN connector for attaching to the meter.Uses MA841 D.O. Replacement Membranes Only.
