Extech DO610: ExStik® II DO/pH/Conductivity Kit
Measures Dissolved Oxygen, pH, Conductivity, TDS, Salinity and Temperature
Extech DO610 measures dissolved oxygen, pH, conductivity, TDS, salinity and temperature
Note salinity is to 10ppt, so this is not suitable for seawater.
Extech DO700: Portable Dissolved Oxygen Meter
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.
Note that with only 1 connection, the probes need to be changed to read either oxygen or pH (mV & temperature) or conductivity.
