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.

JMS-CLM Type II Automatic Online Coliform Monitoring Instrument

Based on the enzyme-substrate detection principle, this product employs continuous spectrophotometric dynamic measurement to monitor color changes or detect fluorescence. The results are automatically calculated according to the degree of color change. The product meets the requirements of standards HJ347.2-2018, HJ1001-2018, and GB18466-2005. Users can select total coliforms, thermotolerant (fecal) coliforms, Escherichia coli, and total colony counts as needed, enabling precise determination of microbial populations in surface water, groundwater, domestic sewage, industrial wastewater, and medical wastewater.

JMPN T12 High-Throughput Microbial Automated Analyzer

The JMPN T12 automated microbial analyzer is based on the traditional multiple-tube fermentation method (MPN method). It features automated temperature control to maintain a constant incubation temperature, ensuring that culture conditions comply with the national standard (GB/T 5750-2023). The instrument also incorporates image-based visual recognition technology to detect acid and gas production. Ultimately, it leverages data analysis techniques to enable rapid, quantitative detection of microorganisms. By combining constant-temperature incubation, sensor monitoring, and intelligent algorithms, this instrument standardizes and automates laboratory microbial testing, significantly improving efficiency and reducing human error. It is applicable to water sample testing in areas such as water quality environmental monitoring, drinking water safety, and research laboratories.
