Milwaukee MC810US MAX pH/TDS/Temp Monitor

ACCURATE. SIMPLE. RELIABLE. 24/7 pH/TDS/TEMP MONITORING.

The Milwaukee MC810US MAX pH/TDS/Temp Monitor lets you monitor pH, TDS, and temperature levels 24/7 automatically. Calibrate once and let the monitor do the rest. Preferred for nutrient tanks, hydroponics, and aquariums where continuous multi-parameter monitoring is essential.

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."

DESIGN FEATURES

• Three large backlit LCD readouts displaying pH, TDS, and temperature simultaneously.
• pH accuracy: ±0.2 pH (0.0–12.0 pH range).

• Temperature accuracy: ±0.5°F / ±0.3°C (14–140°F / -10 to 60°C).
• External switch converts EC to TDS using 0.5 or 0.7 conversion factor.
• Two-point pH calibration and one-point TDS calibration via manual trimmers.
• MA911B/2 lab-grade, gel-filled, double junction pH electrode included.
• MA811 fixed TDS probe and stainless steel temperature probe included.
• 6.5-foot probe cables for flexible placement.
• Complete mounting kit with probe holder included.
• 12 VDC power supply included.

CARE AND USE

Storage: Store pH probe cap filled with storage solution or calibration buffer — never tap or DI water. Store upright.

Cleaning: Soak pH electrode regularly in cleaning solution to remove residue from sensing bulb and reference junction.

Calibration: Calibrate regularly and always after cleaning or extended storage.

Frequently Asked Questions

Q: What parameters does the Milwaukee MC810US MAX monitor simultaneously?
A: The MC810US MAX displays pH (0.0–12.0), TDS (0–1990 ppm), and temperature (14–140°F / -10 to 60°C) simultaneously on three large backlit LCD readouts — all from a single wall-mounted unit. This makes it the ideal 24/7 monitoring solution for hydroponic nutrient reservoirs, aquariums, and any application where continuous multi-parameter water quality data is needed at a glance.

Q: How accurate is the MC810US MAX and how do I calibrate it?
A: The MC810US MAX delivers ±0.2 pH accuracy (2-point manual calibration), ±2% full scale TDS accuracy (1-point manual calibration), and ±0.5°F temperature accuracy (factory calibrated). Manual trimmers make calibration straightforward. Calibrate pH and TDS before first use and after any extended storage period.

Q: Does the MC810US MAX include all probes needed for monitoring?
A: Yes. The MC810US MAX comes complete with the MA911B/2 lab-grade double junction pH electrode, the MA811 fixed TDS probe, and a fixed stainless steel temperature probe — all with 6.5-foot cables. An external switch on the unit lets you select between 0.5 and 0.7 EC-to-TDS conversion factors to match your specific nutrient solution.

Q: Can I use the MC810US MAX for remote monitoring?
A: Yes — field users report pointing a camera at the MC810US MAX display and monitoring readings remotely via phone. The three large backlit LCD readouts are clearly visible from a distance, making remote visual monitoring practical in grow rooms, greenhouses, and equipment rooms without additional smart connectivity hardware.
