DDS-307 (digital) conductivity meter DDS-307 (digital)conductivity M

A, performance characteristics:

DDS-307 type conductivity meter (hereinafter referred to as the instrument) is a laboratory conductivitymeasuring instruments, it is widely used in petroleum chemical industry, biological medicine, sewage treatment, environmental monitoring, smelting and other industries and universities and research institutions. Ifequipped with appropriate electrode constant, also can be used for measuring electronic semiconductor, pure water nuclear power industry and power plants or ultra pure water conductivity.

The main feature of the instrument:

◆ four ranges, automatic switching, automatic carrydisplay, simple operation, high measurement precision.

◆ automatic temperature measurement and display,automatic temperature compensation is carried out on the solution.

◆ adopts the 31/2 LCD digital display with blue backlight, temperature, and the measured value at the same time display, clear display.

◆ can be set on the solution temperature coefficient and the constant of electrode.
