Description: This advanced multi-functional water analysis tool is designed to provide comprehensive monitoring of various water quality parameters. It is ideal for researchers, environmentalists, and professionals in agriculture and aquaculture industries, ensuring precise and reliable water quality assessment. Features: Functions: Measures multiple parameters including Hydrogen (H2), Temperature, Oxidation-Reduction Potential (ORP), Electrical Conductivity (EC), Total Dissolved Solids (TDS), Salinity, Specific (S.G.), pH, Resistivity, and Nutrient Solution Fertility. pH Range: 0.00-14.00, allowing for broad acid-base measurement. Temperature Range: 0.1℃ to 60℃ (31.2℉ to 140.0℉), suitable for various environmental conditions. EC Range: 0 to 20000 µS/cm, for precise conductivity measurements. TDS Range: 0 to 20000 ppm, to assess total dissolved solids. ORP Range: ±1999 mV, for oxidation-reduction potential. Salinity Range: 0-20%, to measure salt concentration. S.G. Range: 1.000 to 1.222, for specific assessments. H2 Range: 0 to 2400 ppb, measuring hydrogen concentration. Resistivity: 50Ω to 20 kΩ, for detecting water resistivity. Nutrient Solution Fertility: 0-3, essential for agricultural applications. Three button batteries are required and are not included in the delivery. Color: As shown Material: plastic Package Contents: 1x water quality detector Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
