DDS-307 Laboratory Conductivity Meter
DDS-307 Laboratory Conductivity Meter is a laboratory conductivity measuring instrument; it is widely used in petrochemical industry, bio-medicine, sewage treatment, environmental monitoring, mining, smelting and other industries as well as tertiary institutions and research institutes. If it is equipped with the conductivity electrode with appropriate constant, it can also be used for measuring the conductivity of pure water or ultra-pure water in electronic semiconductors, nuclear power industry and power plants.
Features
| The instrument is featured by four-level range, auto-switching, automatic carry digital display, simple operation |
| and high measurement accuracy. |
| The instrument can measure and display the temperature and conducts temperature compensation of the solution |
| automatically. |
| The instrument adopts three-digit liquid crystal digital display; the temperature and the measurement values are |
| displayed simultaneously. Its external shape is beautiful, and its display is clear. |
| The user can use the instrument to set the constants of electrodes and the temperature coefficient of the solution. |
