Accurate. Simple. Reliable. 24/7 pH/EC/Temp Monitoring.

Why Guard when you can Monitor! The Milwaukee MC811 MAX pH/EC/Temp Monitor lets you monitor your pH/EC/Temp levels 24/7 automatically.

Comments From Field Testing

"I run this unit 24/7 and have not had any problems for the past two months. I can monitor 24/7, point a camera on it and connect to my phone."

"Easy to calibrate."

"Using this now, far less expensive than what my friends paid ... I recommend this to any serious grower."

Summary

The MC811 MAX Monitor automatically monitors and displays pH/EC/Temp levels.  Just calibrate the parameters and let the Milwaukee MAX Monitor do the rest.

The Milwaukee MC811 MAX pH/EC/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/EC/Temp Monitor offers:

Accuracy

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

Automation

Just calibrate the parameters and begin to monitor 24/7!

Easy installation

The MC811 MAX pH/EC/Temp Monitor comes with a complete mounting kit including a probe holder.  For local plug conversion, you will need to source an EU to AU plug converter. 

Design features

• Fast easy to read current results with 3 large digital BACKLIT LCD readouts.
• Accurate to ±0.2 pH (0.0 pH to 12.0 pH).
• Accurate  ±2% Full Scale EC. 
•  
• Simple two-point pH calibration and one point EC, for increased accuracy with manual trimmers for easy adjustment.
• Gel-filled, double junction MA911B/2 (included) lab grade pH electrode for low maintenance and high performance.
• 6.5 feet probe cables for extra flexibility when testing.
• 12 VDC power supply.

 

 

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.

Store the pH probe in storage solution MA9015.  Only use tap water short-term if is not immediately available and NEVER store in distilled Water (DI) or Reverse Osmosis (RO) water. This will damage the sensitivity of the probe.

This best way to store the probe is with the probe's cap filled with MA9015 Storage Solution 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 block the junction. This is especially true if the sample has a lot of organic material. We recommend regularly soaking the probe in MA9016 Cleaning Solution for about 20 minutes.

Calibration

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