Model SX723 Operation Manual
Thanks for buying and using the model SX723 pH/mV/Conductivity 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 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.
Builtin microprocessor chip, beautiful appearance, multifunctional and easy to use, this meter has the following prominent features:
1.1.Double parameters meter, with pH electrode, conductivity electrode, and with calibration solution and special carrying case, easy to use.
1.2.Builtin microprocessor chip, with the inligent functions of automatic calibration, automatic temperature compensation, data storage, function setting and automatic selfdiagnose, auto power off and low voltage display etc.
1.3.Adopts digital filter and step slipping technology to inligently improve meters response speed and result accuracy.
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 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 200mS/cm by using only onepoint 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.Automatically select conductivity measuring range, the meter will do nonlinearity 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. Meters circuit board adopts SMT filmcovering technology to improve meters production reliability.
1.10. Meter has the back light LCD display monitor.
1.11. Dustproof and waterproof meter meets IP57 rating.
