DDS-307 conductivity meter (Digital meter) laboratory DDS-307A | Инструменты

First, the performance characteristics:
DDS-307 type conductivity meter (hereinafter referred to as instrument) is a laboratory conductivity measuring instrument, which is widely used in petroleum chemical industry, biological medicine, sewage treatment, environmental monitoring, mine smelting and other industries and universities and research institutions. If equipped with appropriate electrode constant, also can be used to measure the semiconductor, nuclear power industry and power plant water or ultra pure water conductivity.
The main features of the instrument:
The four speed range, automatic switching, automatic carry display, simple operation, high accuracy of measurement.
The automatic temperature measurement and display, automatic temperature compensation of solution.
It adopts the 31/2 LCD digital display with blue backlight, and temperature measurement shows at the same time, clear display.
