Portable Conductivity/Dissolved Oxygen Meter

Portable Conductivity/Dissolved Oxygen Meter
ELE-726

Introduction:

Double-parameter meter, equipped with conductivity electrode and dissolved oxygen electrode, automatic identification of electrode by meter.
Built-in microprocessor chips, intelligent functions such as automatic calibration, automatic temperature compensation, data storage, function set-up, automatic power-off and low voltage display.
Automatic identification of 8 conductivity standard calibration solutions, two options of standard calibration solutions: Europe and America series and China series.
Adopt advanced conductivity measurement technology, use conductivity electrode of constant K=1, only need one-point calibration and meet the measurement precision requirement of 0.5μS/cm ~ 200 mS/cm.
Ability to switch among conductivity, TDS, salinity and resistivity. Multinomial calculation for TDS and salinity to ensure the conversion precision of the full scale.
Conductivity measurement mode has the function of non-linear temperature compensation for high purity water.
Measurement mode of Dissolved oxygen has the function of automatic temperature compensation, automatic salinity compensation and manual air pressure compensation.
New polarographic type dissolved oxygen electrode can measure temperature, salinity and dissolved oxygen simultaneously, equipped with special dissolved oxygen electrode calibration set, polarization only for 3~5 min.
Meter meets IP57 rating, equipped with calibration solution and portable case.
