Conductivity Sensor

Conductivity refers to the degree to which charge carriers (usually ions) in a liquid or solution are capable of conducting electrical current. It is a measure of the conductivity of a liquid and is commonly used to assess the concentration, purity, and ion content of water quality and solutions. Conductivity sensors are specifically designed to measure conductivity. They typically use two electrodes to pass a current through a sample in a liquid and measure the voltage difference between the two electrodes. According to Ohm's law (current equals voltage divided by resistance), the conductivity value can be calculated by measuring the voltage and knowing the electrode spacing.
The measurement principle of Daruifuno's analog Conductivity Sensor is two electrodes, and the materials are stainless steel and graphite.
Stainless steel conductivity sensors use stainless steel as the construction material for electrodes and sensors. Stainless steel has good corrosion resistance and mechanical strength and is suitable for a wide range of application environments. The K constant is divided into 0.01, 0.1 and 1, and the measurement range is 0.05~20uS/cm, 0.5~200uS/cm and 5~2000uS/cm. 1/2 inch NPT mounting thread, suitable for pipeline installation or flow installation. It can usually be used in ultrapure water, pure water, agricultural irrigation and other industries.

Graphite conductivity sensors use graphite materials as electrodes. Graphite has good electrical conductivity and chemical stability, and can be used in specific applications, such as high temperature or strong acid and alkali environment, with a K constant of 1 and a measurement range of 0~10mS/cm. It is usually used in the conductivity detection of surface water, sewage, cooling towers, etc.
