JMCLM 30 Model – Enzyme Substrate-Based Automatic Monitor
The JMCLM30 Model—A New Automatic Monitor Using the Enzymatic Substrate Method—the enzymatic substrate method is a rapid detection technique based on bacteria-specific enzymatic reactions. Its principle lies in detecting the activity of specific enzymes produced during the metabolic processes of coliform bacteria. These enzymes can break down artificially synthesized substrates added to the culture medium, releasing colored or fluorescent products, thereby indirectly indicating the presence and quantity of target bacteria in the water sample. The instrument uses optical sensors to automatically detect and interpret the results. This method replaces the labor-intensive procedures involved in traditional fermentation-tube assays, offering high sensitivity and significantly shorter testing times compared to conventional multi-tube fermentation methods. It is widely used in microbial detection applications involving domestic wastewater, groundwater, surface water, drinking water, and other similar environments.

Seawater Bathing Area Water Quality Monitoring Plan
As people’s living standards improve and urban leisure and vacation trends gain momentum, famous seaside bathing beaches often become overcrowded during the summer months. Currently, although some monitoring equipment is in place for seawater data and visitor surveillance at these beaches, the former requires manual deployment into the seawater for data collection, making it impossible to achieve real-time, automated data acquisition and alerting. As for the latter, it relies merely on simple video surveillance without any further processing of the video footage. Such monitoring systems thus have limited coverage and generally poor effectiveness. Therefore, there is an urgent need to establish an automated monitoring system for seaside bathing beaches, enabling timely tracking of water quality changes and providing the public with valuable public-service information.
