USE AND CARE
“OPEN AIR” CALIBRATION PROCEDURE FOR THE MW600 DISSOLVED OXYGEN METER
1. Remove the membrane
Take the membrane off the end of the probe and dry the diode off.
2. Zero out the display
Connect the probe to the base unit and turn the unit on. Your display should read 0.0. If it does not, go to the position “0” screw on the front of the unit with the screw driver provided and through the access hole make the unit display read 0.0.
3. Fill the membrane
Go to the membrane and put the “O” ring inside the membrane on the shoulder at the base of the threads. Fill the membrane to just short of the “O” ring with MA9071 electrolyte solution. Be sure that there are no bubbles inside the membrane. (Air bubbles are the main cause of calibration failure)
4. Attach the membrane
Screw the membrane on to the probe.
5. Let stabilize
Turn the meter on and hang the probe off the end of a table pointing down and let the unit display stabilize (this may take 5 to 15 minutes)
6. Adjust
Push down and hold the “Cal” button on the front face of the meter and with the screwdriver go to the front Cal position “100%” and make the display read 100.
You are now calibrated.
EXTRA TIPS
Watch for the membrane having wrinkles or stretch marks. If you see wrinkles, replace with a new membrane.
Always use fresh electrolyte solution (MA9071).
Probe calibration is a simple procedure for optimal performance and should be done any time your readings become suspect. Calibration should be performed at least once a month.

pH Calibration Solutions and Buffer Sachets
Regular pH meter calibration helps compensate for changes in electrode performance over time. Milwaukee pH buffer solutions are available in different reference values to suit the calibration requirements of compatible meters and testers.
Options include:
pH 4.01 calibration solution – an acidic buffer for suitable calibration procedures.
pH 7.01 calibration solution – a neutral reference buffer commonly used for pH calibration.
pH 10.01 calibration solution – an alkaline reference buffer for compatible meters and applications.
Individual sachets provide a convenient, pre-measured quantity of solution. Their sealed packaging helps reduce the risk of contamination associated with repeatedly opening a larger bottle, making them useful for occasional calibration and field testing.
Always follow your meter manufacturer's instructions and use the buffer values specified for your instrument.
EC and Conductivity Calibration Solutions
Conductivity meters are widely used to monitor dissolved ionic content in water, including in hydroponics, aquaculture and water treatment.
Milwaukee conductivity calibration solutions provide known reference values for checking and calibrating compatible EC meters. Available standards include 1413 µS/cm and 12880 µS/cm, allowing users to select a suitable calibration point for their instrument and measurement range.
Choose the calibration value recommended in your meter's manual. Conductivity is temperature-dependent, so follow the manufacturer's temperature compensation and calibration instructions.
TDS Calibration Solutions
TDS meters estimate total dissolved solids using conductivity measurements. For dependable readings, the meter should be calibrated using a suitable TDS reference solution.
Milwaukee TDS calibration sachets provide a convenient way to maintain compatible TDS testers. For example, the 1382 ppm standard can be used with instruments that specify this calibration value.
Check the conversion scale and calibration requirements of your meter before selecting a solution, as TDS readings can vary depending on the conversion factor used.
Electrode Cleaning and Storage Solutions
Calibration is only one part of maintaining a water testing meter. pH and ORP electrodes also need suitable cleaning and storage to help maintain their performance.
GroAqua stocks Milwaukee electrode care products, including:
Electrode cleaning solution – helps remove deposits and residue from sensing surfaces.
Electrode storage solution – helps keep compatible pH and ORP electrodes properly hydrated between uses.
Use the correct cleaning and storage products for your electrode type. Do not store pH electrodes in distilled or deionised water unless the manufacturer specifically instructs you to do so.
Choosing the Correct Milwaukee Calibration Solution
Before ordering, check the model of your meter or tester and confirm the calibration standard specified by its manufacturer.
Consider the following:
Measurement parameter: Select a pH, EC, TDS or other specialist solution to match your instrument.
Calibration value: Check the required buffer or reference value in the meter's instructions.
Packaging: Choose individual sachets for convenient single-use calibration or a bottle where a larger quantity is more suitable.
Electrode maintenance: Consider compatible cleaning and storage solutions as part of your regular maintenance routine.
Expiry and storage: Check the expiry date and follow the storage instructions to help preserve solution quality.
