X51 5-in-1 Portable Pen-Shaped Water Quality Tester: Measures salinity, pH, TDS, and electrical conductivity. High-precision, multifunctional water quality tester.

Whether for drinking water testing, maintaining pool water quality, or monitoring nutrient solution concentrations in hydroponics, the X51 5-in-1 Water Quality Tester meets all your needs. It measures four key parameters (salinity, pH, TDS, and electrical conductivity) and also displays the temperature. This makes it a versatile device for water analysis in various situations. It is the ideal choice for homes, laboratories, and aquaculture operations. 【Five Key Parameters for Comprehensive Water Quality Control】 Thanks to its high-precision probe, it quickly and reliably measures the most important water quality indicators: pH (acid/base): 0.00–14.00, for determining the acid-base balance of the water, suitable for aquariums, swimming pools, and drinking water; TDS (total dissolved solids): 0–9999 ppm, for measuring the total amount of dissolved solids in the water and determining its purity. Conductivity (EC): 0–9999 µS/cm, reflects the ion concentration in the water, for monitoring nutrient solutions in hydroponics and wastewater treatment; Salinity: 0.0–10.0 ppt, measures the salinity of the water, suitable for marine aquaculture and brackish water tanks; Temperature: 0–80 °C, real-time display of water temperature, automatic temperature compensation.
