Product Details

SX751 portable pH/ORP/conductivity/ Dissolved Oxygen Meter

Brief introduction

SX751 is perfect combination of advanced electronic technology, sensor technology and software design. It can meter PH, ORP, conductivity, TDS, salinity, resistivity, dissolved oxygen, temperature and other parameters for high precision measurement of water solution, SX751 is the most cost-effective portable water quality analysis instrument.

Features

1. Built in microprocessor chip, with automatic calibration, automatic temperature compensation, data storage, function settings, self diagnostic information, automatic shutdown and low voltage display and other intelligent functions.

2. Multi parameter instrument configuration, pH electrode, ORP electrode, electrode and oxygen electrode, electrode automatic identification instrument.

3. Automatic identification of 13 kinds of pH standard buffer solution, there are three series of standard buffer solution can choose: Europe and America series, NIST series and China series.

4. Can set the high pure water pH measurement mode and ammonia water pH measurement mode.

5. Automatic identification of 8 kinds of electrical conductivity of the standard solution, there are two series of standard solution can choose: Europe and the United States and China series.

6. Using advanced electrical conductivity measurement technology, the use of constant K=1 conductance electrode only a little calibration, can meet the requirements of the measurement accuracy of 0.5 S/cm ~ 200 mS/cm.

7. Can switch electrical conductivity, TDS, salinity and resistivity. TDS and salinity are used to calculate the conversion accuracy of the whole range.

8. Nonlinear temperature compensation function of high purity water in the model of electrical conductivity measurement.

9. The dissolved oxygen measurement model has the function of automatic temperature compensation, automatic salinity compensation and manual air pressure compensation.

10. New structure of polarographic oxygen electrode can be for simultaneous measurement of temperature, salinity and dissolved oxygen, with set to special dissolved oxygen electrode calibration, electrode polarization only 3 to 5 minutes.

11. The instrument conforms to the IP57 waterproof level, the configuration of the solution and the suitcase.
