Milwaukee’s MW804 MAX is a waterproof multiparameter pH/conductivity/TDS tester in an ergonomic design. This meter has advanced features including automatic calibration and temperature compensation. All pH readings are displayed with a 0.01 pH resolution and accurate to ±0.05 pH. Conductivity is measured up to 19.99 mS/cm and can be converted to a TDS reading using either the default (0.5) or user defined factor. The large multi level LCD displays the batterylevel at start up and then either pH, EC, or TDS and temperature along with a stability indicator to alert the user when a stable reading is obtained. The pH/EC/TDS probe is replaceable.
- Accurate Measurements: pH is accurate to ±0.05, EC/TDS 2% full scale and temperature ±0.5 °C / ±1 °F
- Meter Range: 0.00 – 14.00 pH, EC 20.00 mS/cm, TDS 0 – 10.00 ppt, Temperature: 0.0 to 50.0 °C / 32.0 to 122.0 °F
- Stability: Automactic stability indicator lets the user know when a stable reading has been obtained
- Long-Lasting: Waterproof, lightweight, and probes are replaceable
For acid Based calibrations, cleaning & storage solutions use PH-START add MA9010 (10.01 cal. buffer) or M10010B if Basic cal. required. For EC calibration use MA9060 12,880 µS/cm or M10030B µS/cm.
