This meter is a perfect combination with the most advanced electronic technology, sensor technology and software design, it is the best pH, mV and conductivity meter with the highest performance and the lowest cost. It is suitable for measuring the pH and conductivity value of laboratory common aqueous solution, also can test the electric potential of various ion selective electrodes.
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 and automatic self-diagnose 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. Automatically recognize pH standard buffer solution. User can choose anyone from three series of buffer solutions: Europe & U.S.A. series, NIST series and CHINA series.
1.4. 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.
1.5. Meter’s circuit board adopts SMT film-covering technology to improve meter’s production reliability.
1.6. Meter has the only product series number.
1.7. Dustproof and waterproof meter meets IP54 rating. All sockets are seal protected by the silica gel caps.
