Milwaukee Eco pH Meter – Economical pH Meter for Nutrient Solution in Culture

Frequently asked questions

• What does the Milwaukee PH600 offer for its price?

  It's an affordable pH meter that gives quick, accurate readings across a range of 0.0 to 14.0 pH. It stands out for its resolution and accuracy of 0.1 pH and for being able to work between 0 and 50 ºC. A perfect entry point if you want to control pH without overspending.

• How do you take a measurement with the PH600?

  Remove the black protective cap, turn on the meter and submerge it up to the indicated limit. Wait for the reading to stabilize and note the value. Then clean the electrode with water before storing it.

• How do you calibrate it?

  Submerge the electrode in the pH 7.01 calibration liquid (reference M10007), wait for the reading to stabilize and adjust to pH 7.0 with the screwdriver located on the back. Always use fresh calibration liquids so the adjustment is accurate. It's a quick process that should be repeated regularly.

• How do I store the electrode between uses?

  Apply a few drops of the MA9015 liquid or pH 7.0 calibration liquid to the cap that holds a sponge, and store it this way. Never use distilled or deionized water to store it. Keeping the electrode moist is what guarantees stable readings over time.

• What cleaning does the electrode need?

  Rinse it with running water after each use and, if there's built-up dirt, gently scrub the glass bulb and the transparent band with a soft toothbrush and liquid soap. Every three months, it's a good idea to give it a two-hour bath in cleaning solution (reference M10016B). With this routine, the meter stays accurate for a long time.

• What should I do if the readings vary a lot or it doesn't turn on?

  Significant variations usually indicate that it needs recalibration, that the electrode is dry, or that the batteries are low. If it doesn't turn on or the display looks weak, open the compartment and replace the three 1.5 V batteries, respecting the polarity. This usually solves the problem.
