Description
Overview
GAOTek digital ion sensor for water quality monitoring is a digital ion sensor with RS485 communication and standard Modbus protocol. Housing material is corrosion-resistant (PPS+POM), IP68 protection, suitable for most water quality monitoring environments; This online ion sensor uses an industrial-grade composite electrode, the reference electrode double salt bridge design and have longer working life; Built-in temperature sensor and compensation algorithm, high precision; It has been widely used in domestic and foreign scientific research institutions, chemical production, agricultural fertilizer, and organic wastewater industries. It is used for the detection of general sewage, wastewater and surface water. It can be installed in sink or flow tank.
