Dustproof and waterproof meter meets IP57 rating.
Prominent Features:
1. Multi-parameter meter, equipped with pH electrode, ORP Electrode, conductivity electrode, temperature electrode, DO electrode, when connect the electrode to the meter, the meter can automatically know the electrode, easy to use.
2. Built-in microprocessor chip.. Its features up to automatic calibration, automatic temperature compensation, data storage, auto power off, low voltage indication, functions setting and automatic self-diagnose etc.
3. 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.
4. 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.
5. 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 one-point calibration. It is the particular one–point calibration function for this meter.
6. Automatically recognize 8 kinds of conductivity standard solution. User can choose anyone from two series of standard solutions: Europe & USA series and CHINA series.
7. Automatically 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.
8. 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 Atmospheric pressure compensation inside meter, easy to use, accurate to measure.
9. 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.
10. Meter’s circuit board adopts SMT film-covering technology to improve meter’s production reliability.
11. Meter has the back light LCD display monitor.
12. Dustproof and waterproof meter meets IP57 rating.
