DDG-403D conductivity meter

DDG-403D conductivity meter

Overview

The DDG-403D conductivity meter is an intelligent conductivity measurement and control instrument that uses a microcontroller for measurement and temperature compensation. It features a large backlit LCD display with Chinese prompts for operation. Widely applicable for measuring and monitoring industrial online conductivity in water production industries such as electronics, chemical, pharmaceutical, electromechanical, nuclear energy, and drinking water.
