Four instruments in one!
pH, conductivity, TDS and temperature,
all in one waterproof meter with a single probe.
This new generation instrument offers unparalleled versatility and simplicity in pH, EC, TDS, and temperature measurement. There are only 2 buttons, yet you can select from a range of calibration buffers and even the temperature scale (°C or °F) most familiar to you. The housing is waterproof and rated for IP 67 conditions. The multi-functional probe includes pH, EC/TDS and temperature in one convenient, rugged handle.
Typical outdoor applications include the fields of agriculture, hydroponics, swimming pools and spas, and environmental analysis. Indoor testing areas include boilers, cooling towers and the printing industry.
