Product Introduction

AMT-PH300 Factory Direct High-Cost-Performance pH Sensor – Universal Electrode / Quick-Connect Interface / In-Stock Supply Supports Mixed Batches
The pH value is one of the most commonly used water quality testing indicators. The pH of natural water is mostly in the range of 6 to 9; the pH of drinking water is required to be between 6.5 and 8.5; the pH of some industrial water should be maintained between 7.0 and 8.5, otherwise it will cause corrosion to metal equipment and pipelines. pH value is both different from and related to acidity and alkalinity. pH value indicates the strength of acidity or alkalinity of water, while acidity or alkalinity refers to the content of acidic or alkaline substances in water. Changes in the pH value of water quality indicate the degree of water pollution.

The direct relationship between human health and pH value is not clear, but pH value can affect health by influencing other water quality indicators and water treatment effectiveness.

A pH value in the range of 6.5 to 9.5 does not affect drinking or health, but a pH value that is too low can corrode water pipes, while a pH value that is too high can cause dissolved salts to precipitate and reduce the effectiveness of chlorination disinfection. According to surveys, the pH value of most natural waters in China ranges from 6.5 to 8.5, so China's 'Standards for Drinking Water Quality' stipulates that the pH value should be between 6.5 and 8.5.

This product is an upgraded intelligent version of the acidity meter, capable of continuous measurement and control of pH values in water quality and wastewater.
