This meter is a perfect combination with the most advanced electronic technology, sensor technology and software design. It is the best lab conductivity and DO double-parameter device with the highest performance and the lowest cost. It is suitable for the trade such as the petroleum, chemical industry, medicine, power plant and environmental protection, etc., especially has more extensive application in the fields of education and scientific research.
Built-in microprocessor chip, beautiful appearance, multi-functional and easy to use, this meter has the following prominent features:
1.1. Meter meets with the requirement of international GLP standards. Its features up to automatic calibration, automatic temperature compensation, data storage, timing measurement, RS-232 output, clock display, function setting etc.

1.2.  Adopts digital filter and step slipping technology to intelligently improve meter’s response speed and result accuracy. “     ” will appear when reading to be stable.
1.3.  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 100mS/cm by using only one-point calibration. It is the particular one–point calibration function for this meter.
1.4. Automatically recognize 8 kinds of conductivity standard solution. User can choose anyone from two series of buffer solutions: Europe & U.S.A. series and CHINA series.
1.5. Automatic select conductivity measuring range, the meter will do non-linearity temperature compensation test for high purified water less than 10μS/cm, which greatly improve the measuring accuracy. It is especially suitable for use in fields of electric power, microelectronics and medicine.
1.6.  Equips new type of DO electrode which has function of automatic temperature compensation and automatic salinity compensation as well as automatic air pressure compensation inside meter to make DO measuring mode has temperature, air pressure and salinity automatic compensation, easy to use, accurate to measure.
1.7. 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.
1.8. Meter’s circuit board adopts SMT film-covering technology to improve meter’s production reliability.
1.9.  Meter has the only product series number.
1.10. Dustproof and waterproof meter meets IP54 rating. All sockets are seal protected by the silica gel caps.
