产品描述

Product introduction:

The multi parameter instrument configuration, pH electrode, electrode and oxygen electrode, electrode automatic identification instrument.

The built-in microprocessor chip, with automatic calibration, automatic temperature compensation, data storage, function setting, self diagnosis information, automatic shutdown and low voltage display intelligent function.

The automatic identification of 13 kinds of pH standard buffer solution, a standard buffer solution three series can choose: European and American series, NIST series and China series.

Can be set high pure water pH measurement mode and ammonia water pH measurement mode.

The automatic identification of 8 kinds of electrical conductivity of standard solution, standard solution two series can choose: European and American series and China series.

Adopt the conductivity measurement technology, the use of K=1 electrode constant only one point calibration, can meet the measurement accuracy of 0.5 S/cm ~ 200 mS/cm requirements.

The switchable conductivity, TDS, salinity and resistivity. TDS and salinity is calculated using the polynomial, to ensure the full range conversion accuracy.

The model has high water conductivity measurement of nonlinear temperature compensation function.

The dissolved oxygen measurement mode with automatic temperature compensation, automatic salinity compensation and manual pressure compensation function.

Polarographic oxygen electrode of the new structure can simultaneously measure temperature, salinity and dissolved oxygen, the dissolved oxygen electrode with a special calibration set, the electrode polarization only 3~5 min.

The instrument with IP57 waterproof grade, configuration and calibration solution suitcase.
