DDB-305 portable conductivity meter

1、 Performance characteristics:

The DDB-305 portable conductivity meter is a laboratory conductivity measuring instrument widely used in industries such as petrochemicals, biomedicine, wastewater treatment, environmental monitoring, mining and smelting, as well as in colleges, universities, and research institutions. If equipped with appropriate constant conductivity electrodes, it can be used to measure the conductivity of pure or ultrapure water in electronic semiconductors, nuclear energy industry, and power plants.
The main features of the instrument are:
Four range, automatic switching, automatic carry display, simple operation, high measurement accuracy.
Powered by four No. 5 dry batteries, it is easy to carry and can be used in the field.
Adopting a 3 1/2 digit LCD digital display, temperature and measurement values are displayed simultaneously, with a beautiful appearance and clear display.
The temperature coefficient and electrode constant of the solution can be set.
