Waterproof Galvanic Dissolved Oxygen Meter With Automatic Calibration 0.0 to 45.00 Mg/l (ppm)

The Portable Oximeter is one of Milwaukee’s most popular meters with its reliable and fast operation as well as its 0.0 to 45.00 Mg/l (ppm) accuracy.

The Portable Oximeter Milwaukee MW605 MAX DO Meter is preferred by people looking for lab-level accuracy without the cost. The Milwaukee DO Meter is popular with everyone from field biologists, educators, fish farmers, koi pond owners, water treatment plants and labs.

• Altitude and Salinity compensation.
• Automatic temperature compensation °F & °C.
• Uses MA860 (included) reinforced Galvanic probe with an oxygen-permeable polytetrafluroethylene (PTFE) membrane sensor.
• 2 O-rings, membranes and one protective cap included.
• 10 feet probe cable for extra flexibility when testing.
• 3 x 1.5 volt akaline AA battery (battery included) aprox. 200 hours of battery life with continuous use with low battery warning.

CARE AND MAINTENANCE

PROBE MAINTENANCE:

• The silver cathode should always be bright and untarnished.  If it is tarnished or stained, the cathode should be cleaned gently with a lint-free cloth.
• Rinse the probe with deionized or distilled water.
• Replace the membrane cap using fresh electrolytes.
• Recalibrate meter.

Membrane Maintenance:

• For accurate and stable measurements, the perfect condition of the membrane surface is needed.  Protect the thin membrane from scratches, abrasion or contact with solids.
• If no measurements are taken for a few hours, protect the membrane with the plastic protective cap.
• If fouled, rinse it carefully with distilled or deionized water.  If damaged, replace the membrane cap.

Note:  Change the membrane every 8 weeks or more frequently if used in a specially fouling environment.  Check and replace the electrolyte fill solution every 4 weeks.

Storage:

After taking measurements, switch the meter off and clean the probe before storage.  When not in use the probe should be stored with the plastic cap on.

For short-term storage, the probe can also be stored in a beaker of deionized water with the protective plastic cap removed.

For long-term storage, the probe should be stored dry:

1. Disconnect the probe from the meter.

2.  Unscrew the membrane cap.

3.  Remove any electrolyte solution from the cap.

4.  Rinse the probe anode/cathode assembly with distilled water and blot dry.

5.  Screw the membrane cap onto the probe until the membrane cap is hand-tight.
