T6700 dual-channel controller
Function
This instrument is an intelligent online controller, which is widely used in water quality detection in sewage plants,waterworks,water stations, surface water and other fields, as well as electronic, electroplating, printing and dyeing, chemistry,food, pharmaceutical and other process fields, meet the needs of water quality detection; Adopting digital and modular design,different functions are completed by various unique modules. Built-in more than 20 kinds of sensors, which can be combined at will, and reserved powerful expansion functions.
Typical Use
This instrument is a special instrument for detecting oxygen content in liquids in environmental protection sewage related industries. It has the characteristics of fast response, stability, reliability, and low use cost, widely used in large-scale water plants, aeration tanks, aquaculture, and sewage treatment plants.
