Water Quality Meters.
Water Quality Meters determine water quality by measuring various parameters such as pH, temperature, conductivity, salinity, and temperature. They also measure the presence of fluoride, ammonia, nitrate, sodium, and more. Devices vary from simple pH meters to advanced multi-parameter systems.
