pH / TDS / Temperature Monitor

The pH/TDS/Temp Monitor lets you monitor your pH/TDS/Temp levels 24/7 automatically

The Milwaukee MC810 MAX Monitor is widely recognized in hydroponics, aquaculture, and laboratory settings for providing continuous, real-time pH, TDS, and temperature readings. Scientific studies on nutrient solution management highlight that consistent monitoring of pH and total dissolved solids (TDS) is crucial for plant health and water quality, which this monitor facilitates. Industry reviews and customer feedback consistently praise the MC810 MAX for its reliability, ease of use, and robust performance in both professional and hobbyist applications. It is commonly used for nutrient tanks, aquariums, and hydroponic systems, with users noting improved accuracy in nutrient management and simplified daily monitoring routines.

The MC810 MAX Monitor automatically monitors and displays pH/TDS/Temperature levels. Just calibrate the parameters and let the Milwaukee MAX Monitor do the rest. The Milwaukee MC810 MAX pH/TDS/Temp Monitor is preferred by people looking to know 24/7 what their pH and nutrient levels are on an ongoing basis. Common uses are nutrient tanks, Hydroponics and aquariums. The Milwaukee MAX pH/TDS/Temp Monitor offers:

To expand your water quality and parameter monitoring toolkit beyond the pH‑TDS‑Temperature Monitor — an instrument that measures pH, total dissolved solids (TDS) and temperature in one unit for comprehensive analysis — consider additional high‑performance water quality meters that enhance measurement depth and flexibility. The Portable pH/EC/TDS/Temperature Meter with CAL Check™ offers combined pH, conductivity (EC), TDS and temperature sensing with built‑in calibration diagnostics, ideal for field and process environments. For advanced multi‑parameter monitoring that includes dissolved oxygen, turbidity, and other key water quality indicators, the Multiparameter Water Quality Meter delivers broad analytical capability across pH, EC, TDS and more. Additionally, the Benchtop Dissolved Oxygen Meter provides laboratory‑grade dissolved oxygen measurement to complement pH and TDS data for complete aquatic quality assessment.

ACCURACY

The Milwaukee MAX Monitor offers an accuracy to ± 0.2 pH with two-point manual calibration, TDS accuracy of ±2% Full Scale, and ±0.5 °F (0.3 °C) temperature accuracy.

pH/TDS/Temp Monitor USE AND CARE

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 or DI water, as 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 calibration buffer and the cap tightened to prevent leakage. It is also recommended 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 regularly to keep your PRO pH controller accurate. Also, calibrate after cleaning or a long period of storage.

Q&A

What is the ideal calibration frequency for the MC810 MAX Monitor?

For best results, calibrate the pH and TDS probes at least once a week, or after cleaning or long-term storage, to maintain measurement accuracy.

Can this monitor be used in aquariums with fish?

Yes, the MC810 MAX is suitable for aquariums, as it provides continuous monitoring of pH, TDS, and temperature without harming aquatic life.

How long does the pH electrode typically last?

With proper storage and maintenance, the gel-filled double-junction pH electrode can last 1–2 years, depending on usage and water quality.

Is the monitor suitable for hydroponic nutrient tanks?

Absolutely. It is commonly used in hydroponics to monitor nutrient solutions 24/7, helping maintain optimal growth conditions for plants.

Does the device require professional installation?

No, the MC810 MAX comes with a complete mounting kit and is designed for easy DIY installation and setup.
