The MJ-WQA100 water quality analyzer is designed and manufactured by MJ Instruments Private Limited. Equipped with high-end CPU and a precise signal processor which greatly reduce signal fluctuation, improving the data stability and accuracy. The compartments are carefully designed so that both water and electrical components are separated to ensure long operational life of the analyzers.

MJ-WQA100 water quality analyzer allow customisation of multiple parameters in a single unit analyzer, it lowers the initial capital cost of the water quality monitoring solution and the flexibility of smaller footprint. The application of the analyzer includes surface water monitoring, seawater monitoring, groundwater monitoring, wastewater plant, pollution control, researches studies, rainwater monitoring and etc.
