MA845 | DO Probe

The Milwaukee MA845 is a polarographic replacement probe for the MW190 MAX Dissolved Oxygen 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.

• 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.
