Product Overview:
An automatic water quality sampler is an intelligent device used for the automated collection of water samples. It is primarily applied in the field of environmental monitoring, such as in rivers, lakes, industrial wastewater discharge outlets, and other scenarios. It serves as a supervisory tool for environmental monitoring and scientific research departments to accurately regulate wastewater discharge from chemical enterprises. The design of the automatic water quality sampler complies with the national standard HJ/T 372-2007. Controlled by a microcomputer and equipped with a high-precision peristaltic pump, it supports various sampling, analytical supply, and sample preservation modes, including timed, fixed-flow, and proportional sampling. It also enables remote control and data communication.
