The MW-MW804 pocket tester with dual-level LCD measures pH/ Conductivity/TDS/Temperature. 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 (MW804) 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 and  horticultural applications they can also be used in Industrial and Laboratory applications such as cooling towers, food processing, plating, drinking and waste water etc.
