The differences in natural environment in different regions lead to different water quality conditions in different regions. Safe and healthy water quality is the common pursuit of all regions, especially in the use of drinking water. The water environment in many regions is unstable due to natural and human factors. In order to ensure the safety of residents' water use, create a healthy water environment, and ensure orderly production and life, more and more communities, industrial parks and enterprises are installing drinking water multi-parameter water quality monitoring instruments to ensure the safety of inlet and outlet water quality.

1. Background introduction

In the pursuit of sustainable development today, smart agriculture has become an important trend in global agricultural development. Among them, the intelligent tea garden environmental data monitoring system, as an important part of intelligent agriculture, is leading the green revolution of the tea industry with its special charm and potential.

With the rapid development of industrialization and urbanization, air quality has been paid more and more attention. As a key tool for measuring and evaluating air quality, the innovative application of air quality monitoring equipment can not only help us better understand the state of air quality, but also provide strong support for environmental protection and public health. Here are a few examples of innovative applications of air quality monitoring equipment.

The significance of rural domestic sewage monitoring

Rural domestic sewage mainly includes black water (human feces and urine and flushing water), bathing water, laundry wastewater and gray water (kitchen wastewater), which is one of the main pollutants affecting the quality of rural ecological environment.

1.Product Principle

The pH meter measures the pH value of a solution using the potentiometric method. The main components involved in the measurement of the pH meter are the glass electrode and the reference electrode. 

The ocean is the largest body of water on Earth and plays an important role in human survival and development.
