Milwaukee MW806 Max 4-in-1 Combi Meter / Datalogger with USB (pH, EC, TDS and Temperature)

The Milwaukee MW806 Max is an easy to operate professional portable combi meter with a USB connection and a data logger function. With the MW806 Max 4-in-1 you can measure the pH / EC / TDS and temperature and if desired save it on the meter and / or export to a PC.

Measuring pH and EC is very important for growers. The pH value of the nutrient solution has an effect on the absorption of nutrients and water. An incorrect pH value impairs the effectiveness of nutrients, herbicides and pesticides. Monitoring the EC facilitates the dosing of plant nutrients and provides better insight into the absorption and consumption of the nutrients.

With the Milwaukee MW806 Max 4-in-1 Combi meter you can easily, quickly and precisely measure the pH value (acidity), EC value (conductivity), TDS (total dissolved solids) and temperature with only one meter and one electrode.

Simple, portable, rugged! The Milwaukee MW806 Max is the ultimate solution for managing pH and nutrient solutions. No more fumbling with multiple meters or electrodes. The MW806 Max also features automatic temperature compensation (ATC).

Characteristics

• Specially designed for hydroponics, aquaponics and greenhouses.

Use and care
The MW806 Max is delivered including the MA852D/1 electrode. Proper maintenance of the electrode ensures that it measures for a long time, quickly and accurately. Every pH sensor has a limited life 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, therefore, 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.
