Applications

The versatility of the MC811 MAX makes it suitable for a wide range of applications:

Agriculture & Hydroponics

Maintaining optimal nutrient levels is crucial for plant health. The MC811 MAX allows growers to monitor and adjust pH and EC levels in nutrient solutions, ensuring plants receive the right balance of nutrients for maximum yield.

Aquariums & Aquaculture

Aquatic life thrives in stable environments. The MC811 MAX helps aquarists and fish farmers maintain ideal water conditions by continuously monitoring pH, EC, and temperature, preventing harmful fluctuations that could stress or harm aquatic organisms.

Water Treatment & Purification

In water treatment facilities, monitoring pH and EC is essential for assessing water quality and treatment efficiency. The MC811 MAX provides real-time data, aiding in the optimization of purification processes and ensuring compliance with water quality standards.

Food & Beverage Industry

Water quality directly impacts product taste and safety. The MC811 MAX assists in monitoring the pH and EC of water used in food and beverage production, ensuring consistency and adherence to quality control measures.

Laboratories & Research

For scientific experiments requiring precise water quality conditions, the MC811 MAX offers reliable monitoring of pH, EC, and temperature, supporting accurate and reproducible research outcomes.

Environmental Monitoring

Environmental scientists can utilize the MC811 MAX to monitor natural water bodies, detecting changes in pH and EC that may indicate pollution or ecological shifts, thereby aiding in environmental protection efforts.

Proper Care & Maintenance

pH meters usually start performing poorly because of problems with the probe. The two parts of the pH probe that cause problems are the glass sensing bulb and the reference junction.

Sensing bulb

The glass bulb loses sensitivity with use and will eventually fail. This is true of all pH probes.

Reference junction

The reference junction is a small hole that allows the meter to compare the sample to a reference. The reading is generated based on the electrical difference between the sample and reference. If the junction hole gets clogged, the pH probe will no longer function.

You can extend the life of your pH electrode in the following ways.

Storage

The pH probe needs to be kept hydrated. Long periods of dry storage will damage the sensitivity of the probe. Allowing the probe to dry out may also result in the junction hole getting clogged.

Storing in pH probe storage solution or pH calibration buffers will help address both these issues. Do not store in tap water and DI water. This will damage the sensitivity of the probe.

The best way to store the probe is with the probe's cap filled with storage solution or calibiration buffer and the cap tightened to prevent leakage. It is also recommended that to store the electrode upright to further reduce the potential for leakage.

Cleaning

Residue from the sample can impact the sensitivity of the sensing bulb and clog the junction. This is especially true if the sample has a lot of organic material. We recommend regularly soaking your electrode in cleaning solution.

Calibration

The pH sensing bulbs become less sensitive over time so make sure that you are calibrating reguarly to keep your MAX monitor accurate. Also, calibrate after cleaning or a long period of storage.

Enhance your water quality monitoring with the Milwaukee MC811 MAX – precision, reliability, and ease of use in one comprehensive solution.
