Description

9-in-1 Meter with Lab Performance

The 9-in-1 DO700 Kit measures DO concentration/saturation, pH, mV, Temperature, Conductivity, TDS, Salinity, and Resistivity. It features automatic salinity compensation and manual barometric pressure compensation for DO measurements. In addition, it has automatic one button calibration of 4, 7 and 10 pH with a choice of three-point calibration for better accuracy and it provides automatic temperature compensation. Complete with DO probe, pH/mV/Temp electrode, polymer Conductivity cell, pH and Conductivity calibration solutions, batteries and hard carrying case.
