Extech DO700 Portable Dissolved Oxygen Meter
Introduction of Extech DO700
The 9-in-1 DO700 Kit is a versatile tool that measures DO concentration/saturation, pH, mV, Temperature, Conductivity, TDS, Salinity, and Resistivity. It offers automatic salinity compensation and manual barometric pressure compensation for DO measurements.
The kit also includes automatic one-button calibration for pH at 4, 7, and 10 with an option for three-point calibration to ensure higher accuracy. Additionally, it provides automatic temperature compensation. The kit comes complete with a DO probe, pH/mV/Temp electrode, polymer Conductivity cell, pH and Conductivity calibration solutions, batteries, and a hard carrying case.
