This meter is a perfect combination with the most advanced electronic technology, sensor technology and software design. The meter can measure the parameters of pH, mV, conductivity, TDS, salinity, resistivity, DO and temperature for high accuracy water solution. It is the best portable water analysis meter with the highest performance and the lowest cost. It is suitable for the trade such as the mining industry, power plant, water treatment projects and environmental protection, etc., especially has more extensive application in the field and spot test.
Built-in microprocessor chip, beautiful appearance, multi-functional and easy to use, this meter has the following prominent features:
1.1. Multi-parameter meter, equipped with pH electrode, conductivity electrode, DO electrode, calibration solution and special carrying case, easy to use.
1.2. Built-in microprocessor chip. Its features up to automatic calibration, automatic temperature compensation, data storage, auto power off, low voltage indication, function setting and automatic self-diagnose etc.

1.3. Adopts digital filter and step slipping technology to intelligently improve meter’s response speed and result accuracy. “    ” will appear when reading to be stable.
1.4. Automatically recognize 13 kinds of pH standard buffer solution. User can choose anyone from three series of buffer solutions: Europe & U.S.A. series, NIST series, China series.
1.5. High purified water and ammonia added purified water pH measuring mode can be set up, for this two special pH measuring modes, besides the general slope compensation, also added function of nonlinearity solution temperature compensation to make measurement more accurate, especially suitable for the fields of electric power and petrochemical etc.
1.6. Adopts advanced automatic frequency convertible and voltage regulation technology to enlarge the measuring range 10 times for conductivity electrode which constant K=1. It can meet measuring accuracy requirement for range within 0 to 200mS/cm by using only one-point calibration. It is the particular one–point calibration function for this meter.
