This Milwaukee MW805 MAX pH/EC/TDS/Temp. 4-in-1 combo meter allows you to measure pH, EC (conductivity), TDS and Temp. with a single meter and one single probe.
Features:
- pH, conductivity / nutrient EC, TDS (ppt) with automatic temperature compensation.
- Selectable TDS factors from .40 to 0.8; default value 0.50.
- Stability indicator prompting the user when the readings stabilize.
- Dedicated GLP key to store and recall data on system status.
- A replaceable, Amplified Combination pH/EC/TDS/Temp probe with a single 3 foot cable (1 meter) for easy use (MA852D/1 probe included).
- A cloth junction on the pH sensor to reduce contamination when measuring fertilizer solutions. Gel filled for long lasting measurements.
- A light weight and portable form factor at just 9.2 ounces (260 g) with battery and just over 3 inches wide.
- A large easy to read display.
- Factory calibration for Temperature and simple, highly accurate, single cell automatic, one point calibration for EC and an automatic up to 5 point calibration for pH.
- IP 67 rated rugged case built for field or lab applications.
- Specialized design for hydroponic, aquaponics, and greenhouse growers.
