Model SX726 Operation Manual
Thanks for buying and using the model SX726 Conductivity/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 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.
Builtin microprocessor chip, beautiful appearance, multifunctional and easy to use, this meter has the following prominent features:
1.1. Double parameters meter, equipped with conductivity electrode, DO electrode, calibration solution and special carrying case, easy to use.
1.2. Builtin microprocessor chip. Its features up to functions of automatic calibration, automatic temperature compensation, data storage, function stting, auto power off and low voltage indication etc.
1.3. Adopts digital filter and step slipping technology to inligently improve meters response speed and result accuracy.
1.4. 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 onepoint calibration. It is the particular onepoint calibration function for this meter.
1.5. It automatically recognizes 8 kinds of conductivity standard solution. User can choose anyone from two series of standard solutions: Europe & USA series and China series.
1.6. Automatically select conductivity measuring range, the meter will do nonlinearity temperature compensation test for purified and high purified water less than 10 uS/cm, which greatly improve the measuring accuracy. It is especially suitable for use in fields of electric power, microelectronics and medicine.
1.7. 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.
1.8. 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.
1.9. Meters circuit board adopts SMT filmcovering technology to improve meters production reliability.
1.10. Meter has the blue backlight LCD display.
1.11. Dustproof and waterproof meter meets IP57 rating.
