Product Description
DDBJ-305 Portable Conductivity Meter
It is an instrument used for the measurement of the conductivity of aqueous solution in the laboratory. It is widely used in petrochemical industry, bio-medicine, sewage treatment, environmental monitoring, mining and smelting and other industries as well as junior college institutions and research institutes. If equipped with conductivity electrode with the appropriate constant, it can also be used to measure the conductivity of pure water or ultra-pure water in electronic semiconductor or nuclear power industry and power plants.
Features
1.It is featured by fourth-scale range, auto-switching and automatic carry digital display, |
with simple operation and high measurement accuracy. |
2.It adopts four AA batteries for power supply, easy to carry and suitable for field use in the wild. |
3.It adopts three-digit large LCD digital display, displaying the electrical conductivity and |
the temperature simultaneously. Its external shape is beautiful and its display is clear. |
4.The constant of the electrode and the temperature coefficient of the solution can be set. |
