Product Introduction
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 electode calibration set, polarization only for 3~5 min. |
| ● Meter meets IP57 rating, equipped with calibration solution and portable case. |
