詳細介紹
 Thanks for buying and using the model DO700 DO Meter (the following called “meter” in short).
Before using this meter, please read the operation manual carefully in order to help use and maintain it correctly. On the basis of improving instrument of performance constantly, we reserve the right of changing the content of this manual and accessories in case of not notifying in advance.
 
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.      1.1 Multi-parameter meter, equipped with pH electrode, conductivity electrode and 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 inligently 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 and 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 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.
 
1.6. Adopts advanced automatic frequency convertible and voltage regulation technology to enlarge the measuring range of conductivity electrode which constant K=1 to 10 times. It can meet measuring accuracy requirement for range within 0 to 100mS/cm by using only one-point calibration. It is the particular one–point calibration function for this meter.
 
1.7. Automatically recognize 8 kinds of conductivity standard solution. User can choose anyone from two series of standard solutions: Europe & USA series and CHINA series.
 
1.8.Automatic select conductivity measuring range, the meter will do non-linearity temperature compensation test for purified and high purified water less than 10uS/cm, which greatly improve the measuring accuracy. It is especially suitable for use in fields of electric power, microelectronics and medicine.
 
1.9. Equips new type of DO electrode with temperature and salinity sensor which has function of automatic temperature compensation and automatic salinity compensation as well as manual barometric pressure compensation inside meter, easy to use, accurate to measure.
 
1.10. Polarogram type DO electrode has special electrode calibration cap. Only needs 3 to 5 minutes for electrode polarization. Electrode adopts combination diaphragm cap which very convenient to use. Each DO electrode equips with three spare diaphragms caps.
 
1.11. Meter’s circuit board adopts SMT film-covering technology to improve meter’s production reliability.
 
1.12. Meter has the back light LCD display monitor.
 
1.13. Dustproof and waterproof meter meets IP57 rating.
