Product details
Product Introduction/ Product Introduction
KNF-500/G multi parameter water quality sensor is a multi parameter water quality detection sensor designed by Kenaf Company for surface water, drainage, marine monitoring and other fields, used to detect water quality pH, ORP， Temperature, conductivity, TDS， Dissolved oxygen, turbidity, salinity, SS suspended solids, ammonia nitrogen, total nitrogen, COD，TOC， Multi functional integrated sensor for indicators such as oil, blue-green algae and chlorophyll in water. Five sensors can be installed at the same time. According to different sensor functions, 5-10 water quality indicators can be detected at the same time. It has the advantages of high integration, integrated design, RS485 output and easy maintenance. It is suitable for integrated measurement of portable detection and online monitoring equipment.
Special reminder: Customized shell material is required for seawater use.
