WH-SD Water Colorimeter

WH-SD Water colorimeter consists of a meter and a Colorfulness sensor. The sensor contacts the measured aqueous solution, and the meter shows the chroma value, temperature value and working state of the aqueous solution.

The Chroma electrode adopts RS485 communication interface and Standard Modbus protocol with self-cleaning function. The product can effectively eliminate the external environment light and suspended matter interference, rapid response to water changes. The electrode has the advantages of high precision, good stability, no need of intervention. The  measurement is fast and accurate.

Online colorimeter is an online water quality monitor with a microprocessor. Online colorimeter is an industrial online monitoring instrument designed to measure the chromaticity of inlet and outlet water in municipal sewage, industrial wastewater treatment processes, water plants, etc.

WH-SD Water Colorimeter Working Principle：

The light waves sent by the infrared sensor transmitter are absorbed, reflected and scattered by the object being measured during the transmission process. Only a small part of the light can be irradiated to the receiver. The transmittance of the transmitted light is proportional to the concentration of the solution being measured. The color value is calculated by measuring the transmittance of the transmitted light.
