เครื่องวัดค่ากรดด่าง ความนำไฟฟ้า ออกซิเจนในน้ำ รุ่น SX736

Portable pH/Conductivity/DO Meter

Measurement of parameters such as pH, conductivity, TDS, salinity, resistivity, dissolved oxygen and temperature of water solution, the most cost effective portable analytical instrument.

Introduction

● Multi-parameter meter, equipped with pH electrode, 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, self-diagnose information, automatic power-off and low voltage display.

● Automatic identification of 13 pH standard buffer solutions, three options of standard buffer solutions: Europe and America series, NIST series and China series.

● Able to set pH measurement modes of high purity water and pure water with ammonia.

● 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 waterproof rating, equipped with calibration solution and portable case.
