MW804 Pocket-size pH/Conductivity/TDS/Temperature Meter


pH/Conductivity/TDS/Temperature Meter with replaceable electrode

The MW804 fits in the pocket with dual-level LCD that measures pH / Conductivity / TDS / Temperature in one single tester!

The large display shows readings in an extended range from 0.00 to 14.00 pH and 0 to 3999 μS/cm, 0 to 20.00 mS/cm, 0 to 10.00 ppt  and simultaneously shows temperature from 0.0 to 50.0°C or 32.0 to 122.0°F. They have a stability indicator and hold function that freezes the display for easy and accurate recording. The large display also has graphic symbols to guide you through all operations. The EC/TDS conversion factor is user selectable as well as the temperature compensation coefficient (β).

Ideal for quick and accurate measurements in swimming pools, aquariums, horticultural and food & beverage applications they can also be used in Industrial and Laboratory applications such as cooling towers, food processing, plating, drinking and waste water etc.

MW804 is supplied complete with protective cap, 20 mL pH 4.01 and pH 7.01 sachets of calibration solution, 20 mL 12880 μS/cm calibration solution, batteries and instructions.
