Portable Multiparameter Water Quality Meter LX104PQM is a handheld device designed for quick and accurate testing of key water parameters such as pH, dissolved oxygen (DO), turbidity, conductivity, TDS, salinity, temperature, and ion levels. It is widely used for field testing, laboratory analysis, environmental monitoring, drinking water testing, and aquaculture or industrial water quality assessment.
