This Milwaukee High Range MW806 MAX pH/EC/TDS/Temp. is a 4-in-1 combo meter that allows you to measure pH, EC (conductivity), TDS, and temp. with a single meter and one single probe.

• Automatic temperature compensation for pH, conductivity/nutrient EC, and TDS (ppt).
• TDS factors ranging from.40 to 0.8 are selectable; the default value is 0.50.
• When the readings stabilize, the stability indicator alerts the user.
• A dedicated GLP key for storing and retrieving data on system status.
• A replaceable, amplified pH/EC/TDS/Temp probe with a single 3-foot (1-meter) cable
• The pH sensor has a cloth junction to reduce contamination when measuring fertilizer solutions.
• A lightweight and portable form factor weighing just 9.2 ounces (260 g) with a battery and measuring slightly more than 3 inches wide.
• A large, easily readable display.
• Factory temperature calibration and a simple, highly accurate, single-cell automatic.
• One-point EC calibration and automatic pH calibration up to five points.
• IP 67-rated rugged case designed for field or laboratory use.
• Designed specifically for hydroponic, aquaponic, and greenhouse growers.

1. Always store with the cap full of buffer or storage solution, not water.

2. Clean your probe regularly by soaking it in the cleaning solution.

3. Calibrate after cleaning and/or storage before testing to adjust for changes in the pH and EC sensor.

4. Gently stir the probe in the sample for a faster result.
