Milwaukee's MW803 4-in-1 tester is advanced and accurate for reading pH, conductivity, TDS, and temperature. The meter incudes automatic calibration and temperature compensation for a variety of environments. All pH readings are displayed with a 0.01 pH resolution and accurate to ±0.05 pH. Conductivity is measured in the low range and readings displayed up to 3999 µS/cm. The EC reading can be converted to a TDS reading using either the default (0.5) or a user defined value. The large multi level LCD displays the battery level 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 Readings: Extreme accuracy to ±0.05 pH, EC / TDS 2% Full Scale and Temperature ±0.5 °C / ±1 °F
• Range: 0.00 – 14.00 pH | EC 0 to 3999 µS/cm | TDS 0 - 2000 ppm | Temperature: 0.0 to 50.0 °C / 32.0 to 122.0 °F
• Easy to Use: Simply place the probe in the sample, gently stir, and the stability indicator will let you know when a stable reading has been taken
• Calibration: Automatic 1 or 2 point pH calibration with 5 saved calibration points and simple 1 point EC calibration

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 MA9061 1413 µS/cm or M10031B µS/cm.
