Product Description

Product Description

This meter is a perfect combination of the most advanced electronic technology, sensor technology, and software design. The meter can measure the parameters of pH, ORP, 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 trade such as the mining industry, power plant, water treatment projects, environmental protection, etc., especially has more extensive application in the field and spot test.

 

Features

♦Multi-parameter meter, equipped with pH electrode, ORP Electrode, conductivity electrode, temperature electrode, DO electrode, when connecting the electrode to the meter, the meter can automatically know the electrode, easy to use.
♦Built-in microprocessor chip. Its features up to automatic calibration, automatic temperature compensation, data storage, auto power-off, low voltage indication, function setting, automatic self-diagnose, etc.
♦Adopts digital filter and step slipping technology to intelligently improve meter's response speed and result inaccuracy. a smile logo will appear when reading to be stable.
♦Automatically recognize 13 kinds of pH standard buffer solution. Users can choose anyone from three series of buffer solutions: Europe & U.S.A. series, NIST series, China series.
♦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 temperature 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.
♦Adopts advanced automatic frequency convertible and voltage regulation technology to enlarge the measuring range of conductivity electrode which is constant K=1 to 10 times. It can meet the measuring accuracy requirement for ranges within 0 to 200mS/cm by using only one-point calibration. It is the particular one-point calibration function for this meter.
♦Automatically recognize 8 kinds of conductivity standard solutions. Users can choose anyone from two series of standard solutions: the Europe & USA series and the CHINA series.
♦Automatically select conductivity measuring range, the meter will do a non-linearity temperature compensation test for purified and highly purified water less than 10uS/cm, which greatly improves the measuring accuracy. It is especially suitable for use in the fields of electric power, microelectronics, and medicine.
♦Equips a new type of DO electrode with a temperature and salinity sensor which has the function of automatic temperature compensation and automatic salinity compensation as well as manual Atmospheric pressure compensation inside the meter, easy to use, accurate to measure.
♦Polarogram type DO electrode has a special electrode calibration cap. Only needs 3 to 5 minutes for electrode polarization. Electrode adopts a combination diaphragm cap which is very convenient to use. Each DO electrode equips with three spare diaphragms caps.
♦Meter's circuit board adopts SMT film-covering technology to improve meter production reliability.
♦Meter has the backlight LCD display monitor.
♦Dustproof and waterproof meter meets IP57 rating.
