DDG-2519 Industrial online Conductivity Meter is our company’s latest developed two wire transmitter

type intelligent integrated industrial conductivity meter, which adopts the bran-new design pattern and is

characterized by its high performance and reliability as well as LCD display. This meter is specially

developed for water quality tests in such industries as chemical industry, power stations, electronic

industry and fermentation industry. It can be used with various electrodes with a maximum measuring

range up to 2000uS/cm.

Model DDG-2519 is a kind of industrial conductivity meter for continuous measuring. This meter is

characterized by its high accuracy, fast response, small volume and easy installation and maintenance.

This meter has isolated 4~20mA output, strong interference immunity and long transmission distance

up to 200 meters.

♦ Equipped with the latest single chip microcomputer, this conductivity meter is characterized by its
low power consumption, less peripheral components and high performance, stability and reliability.
♦ It adopts the LCD display. When you push the keys, the conductivity meter can display the
conductivity and temperature values respectively.
♦ Three types of electrode constants can be used in this meter.
♦ The meter has power-failure parameter protection.
♦ The four levels of measuring ranges can shift automatically.
♦ It is available with automatic temperature compensation.
♦ 4~20mA isolated current output.
