PH, mV, conductivity, TDS, salinity, resistivity and temperature are the most cost-effective portable water quality analysis instruments for measuring water solution.
产品描述
| Double parameter meter, configuration of the pH electrode and the 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 instrument with IP57 waterproof grade, configuration and calibration solution suitcase. |
