Milwaukee MC811 MAX 3-in-1 Combi Monitor (pH, EC and Temperature)

The Milwaukee MC811 is an affordable and reliable pH, EC and temperature monitor developed and made in Europe for 24/7 measurements. Thanks to 3 separate and illuminated displays, you always immediately see the measured values. Calibration is also very simple and works by adjusting three potentiometers. The MC811 has two calibration points for pH (pH4.01 and pH7.01) and one for EC.

Calibrate and the MC811 Max does the rest! The Milwaukee MC811 Max is ideal for people who want to know the pH, EC and or Temperature values 24/7 and at a glance. This makes the MC811 Max ideal for nutrient vessels, culture systems and aquariums.

Exactly, that is Milwaukee MC811 Max the pH value is exactly ± 0.2 pH, the EC value is ± 2% and the temperature is exactly ± 0.3°C (0.5°F) thanks to the two point manual calibration.

The MC811 Max is supplied complete including suspension kit and electrode holder.

Characteristics

• Quick and easy reading of the current values on three large backlit LCD displays;
• Wide pH measurement range between pH 0.0 and pH 12.0;
• Exact to ± 0.2 pH and ± 2% EC;
• Simple two point pH calibration and single point EC calibration;
• Very precise thanks to the easily manually adjustable potentiometers;
• Included lab grade gel-filled, dual junction pH electrode MA911 B/2;
• All three electrodes come with two meters of cable (6.5 Ft);
• 12 volt DC power supply.

Use and care
The MC811 Max is supplied including the MA911B/2 electrode. Proper maintenance of the electrode ensures that it measures for a long time, quickly and accurately. Every pH sensor has a limited life span and the measurement speed slows down over time.

EC sensors are more robust and last a very long time. However, they can be influenced by the build-up of residue on the sensor. Below, our most important maintenance tips:

• Always store the electrode with buffer or storage solution (KCi) in the rubber cap and not in (demineralized) water;
• Clean the electrode regularly by dipping it in cleaning fluid;
• Calibrate the electrode after cleaning and/or storage before taking measurements to compensate for deviations in the pH or EC reading of the electrode;
• Gently stir the electrode into the solution to be measured to get a faster measurement.
