Milwaukee MW805 Max pH/EC/TDS/Temperature Testing Device
- pH, conductivity / nutrient EC, TDS (ppt) with automatic temperature compensation
- Selectable TDS factors from .40 to 0.8; defaulet value 0.50
- Stability indicator prompting the user when the readings stabilize
This Milwaukee MW805 MAX pH/EC/TDS/Temp 4-in-1 Combo Meter allows you to measure pH, EC (conductivity), TDS, and temperature with a single meter and one integrated probe.
The Milwaukee MW805 MAX Combo Meter has been referenced in multiple hydroponic and agricultural studies for its accuracy and reliability in measuring pH and nutrient levels. Industry reviews consistently highlight its rugged design, ease of use, and precision, making it a favorite among hydroponic, aquaponic, and greenhouse growers. Popular applications include nutrient management in hydroponics, water quality monitoring in aquaponics, and fertilizer optimization in greenhouse operations. Users frequently note its convenience and durability in both lab and field settings.
pH and conductivity are critical for growers. pH affects plant nutrient and water uptake and can reduce the efficiency of fertilizers, herbicides, and pesticides. Managing conductivity helps growers pinpoint fertilizer and other nutrient requirements for optimal plant growth.
The Milwaukee MW805 MAX Combo Meter lets you easily and accurately test pH, conductivity, and total dissolved solids (TDS) using a single meter and integrated probe. Its simple, portable, and rugged design eliminates the need to juggle multiple electrodes and wires, while automatic temperature compensation ensures precise readings.
The MW805 MAX is the ultimate solution for pH and nutrient management.

To expand your environmental monitoring and process control capabilities beyond the Milwaukee MW805 Temperature Meter — a compact digital thermometer for accurate air and surface temperature measurement — consider other precision instruments that strengthen your laboratory and field data collection workflows. The Benchtop Dissolved Oxygen Meter provides reliable dissolved oxygen analysis for water and process samples, augmenting temperature data with critical aquatic quality insights. For comprehensive environmental monitoring that includes both temperature and humidity, the 2‑Channel Temperature and Humidity Logger enables simultaneous logging of thermal and moisture conditions in controlled environments. Additionally, the RTR‑507B Wireless Temperature and Humidity Logger with High Precision Sensor delivers high‑accuracy environmental measurements with wireless connectivity, supporting responsive monitoring in food storage, HVAC, and process control applications.
CARE AND USE
The MW805 MAX Combo Meter includes both pH and EC sensors in the MA852D/1 integrated probe. Proper maintenance ensures fast, accurate results over a longer lifespan. While EC sensors are robust, residue buildup can affect accuracy, and pH sensors naturally age over time.
Top Four Maintenance Tips:
- Always store the probe with the cap full of buffer or storage solution, not water.
- Clean the probe regularly by soaking it in a cleaning solution.
- Calibrate after cleaning or storage before testing to adjust for any sensor changes.
- Gently stir the probe in the sample for faster stabilization of readings.
