EXTECH DO700: Portable Dissolved Oxygen Meter The 9-in-1

EXTECH DO700: Portable Dissolved Oxygen Meter

The EXTECH DO700 is a professional-grade 9-in-1 multiparameter meter designed for field or laboratory use. This versatile instrument measures Dissolved Oxygen (DO) concentration and saturation, pH, mV, temperature, conductivity, TDS, salinity, and resistivity with precision and reliability. The meter offers automatic salinity compensation and manual barometric pressure compensation for DO readings, ensuring accurate measurements across varying environmental conditions.

It features automatic one-button calibration for pH (at 4, 7, and 10 points) with up to three-point calibration for enhanced accuracy. Its automatic temperature compensation (including nonlinear adjustment for purified water <10 µS/cm) further improves measurement performance.
