Mertani Water Quality Monitoring System 

Mertani Water Quality Monitoring System (WQMS) will assist you in continuously monitoring water quality. This includes parameters such as water pH, water temperature, COD, BOD, DO, TSS, ORP, and more. Based on these parameters, you can make informed decisions to ensure the quality of your water is maintained, whether you are an individual, a company, a government entity, or a specific institution.
