Product Introduction
![]()
Features
1) Online automatic monitoring instrument for water quality with five parameters (pH, turbidity, conductivity, dissolved oxygen, temperature)
2) Conventional multi-parameter online water quality analyzer based on digital sensor technology, widely applied in the monitoring of rivers, lakes, water stations and surface waters. It provides 4 digital measurement channels and can be connected to pH, turbidity, dissolved oxygen and conductivity sensors
3) Featuring a rugged and durable all-aluminum alloy casing and a user-friendly 7-inch IPS touch screen for intuitive operation
4) Supports removable Micro SD storage cards for data maintenance and backup
5) The analyzer integrates built-in expansion interfaces to meet various output signal extension needs and provide users with maximum configuration flexibility for their systems
