HI-98129 is a water resistant tester that offers high accuracy pH, conductivity, total dissolved solids and temperature measurements in a single meter.

The high accuracy EC/TDS graphite conductivity probe provides greater accuracy as it cannot be contaminated by salt deposits in the solution.

Another advantage is the exposed temperature sensor which provides fast response times and guarantees highly accurate temperature compensated readings.
