Conductivity meter - DDS-11A

First, performance characteristics:

DDS-11A type conductivity meter is a laboratory conductivity measuring instruments, it is widely used in petroleum chemical, biological medicine, sewage treatment, environmental monitoring, mining and smelting industries and tertiary institutions and research institutes. If equipped with the appropriate constant conductivity of electrodes can be used to measure the electronic semiconductor, nuclear industry and power plants in pure water or ultra-pure water.

The main features of instrument:

Fourth gear range, automatic switch, automatic into the display, simple operation and high precision. Automatic temperature measurement and display, automatic temperature compensation of the solution

With 3 1 / 2 LCD display, temperature and measurements also showed that appearance, show clear.

Solution temperature can be set constant coefficient and electrode.
