Digital Conductivity Sensor-ZW-Cond1006

 

Product introduction

The digital conductivity sensor is an instrument used to measure the conductivity in a solution or water, based on the conductivity of ions in the solution. When current passes through a solution containing ions, the movement of ions produces conductivity. The conductivity is proportional to the concentration and type of ions in the solution. The built-in temperature sensor automatically adjusts the measurement results to compensate for the effect of temperature on conductivity.

Application areas:

Widely used in fresh water monitoring, industrial heating/cooling, drinking water quality analysis, water treatment, chemical industry, food processing, environmental monitoring and other fields.

Digital Turbidity Sensor-ZW-Turb1006

 

Product introduction

The digital turbidity sensor is an instrument used to measure the concentration of suspended particles in water samples. Usually these particles may be composed of sediment, microorganisms, algae or other organic or inorganic substances, which affect the transparency of water. It works based on the principle of light scattering. The sensor emits light through the water sample, and the suspended particles in the water sample scatter the light. By measuring the intensity of the scattered light, the turbidity of the water sample can be calculated.

ZW-COD1006 UV254 COD/TOC Sensor

 

Product introduction

Many organic substances dissolved in water have an absorption effect on external light. Therefore, by measuring the degree of absorption of these organic substances to 254nm wavelength ultraviolet light, the total amount of organic pollutants in the water can be measured.
