Nine-parameter Mini-water Station Instrument Features
1 Monitoring factors are customizable
Including conventional water quality five parameters and permanganate index, ammonia nitrogen, total phosphorus and total nitrogen, to meet the requirements of conventional monitoring in different scenarios and can increase or decrease monitoring factors according to the needs of the field;
2 outdoor design
Outdoor chassis specification design, not afraid of the wind and the Sun with its own chassis air conditioning, environmental adaptability;
3 built in self cleaning
Built-in self-cleaning function, water vapor flushing and ultrasonic cleaning;
4 Multiple modes of communication
Compatible with a variety of communication modes, strong scalability;
5 It’s a small space
It covers an area of about 1 square meter. Compared with the traditional mini-water station, it covers a small area and can be used to replace the traditional water quality monitoring station
