9-in-1 Water Quality Tester with UV Absorbance for COD/TOC/UV275, EC/TDS/Salinity/GH/S.G./Temp, Water Quality Tester for Home, RV, Hiking, Camping, Travel, Well - Tap, Purified, Ground, Seawater

["9 Critical Parameters in One Pen-Style Tester – Measures COD (0-100mg/L), TOC (0-100mg/L), UV275 (0-1.0au/cm), TDS (0-2000ppm), EC (0-4000µS/cm), Salinity (0-26%), General Hardness (0-1000ppm), Specific Gravity (0.9800-1.2000), and Temperature (0-50°C). Perfect for tap water, purified water, groundwater, seawater, aquaculture, and surface water (non-sewage).","UV Absorbance Technology for Organic Matter Testing – Unlike basic TDS meters, this advanced tester uses UV275 absorbance to estimate Chemical Oxygen Demand (COD) and Total Organic Carbon (TOC). Ideal for homeowners, well owners, and aquarists who need insight into organic pollutants, not just dissolved solids.","Smart 4-Color Scoring System – Instant Water Quality Assessment – The intelligent system evaluates your water and changes the 1.14\" TFT color screen backlight to one of four colors: Excellent, Good, Average, or Poor. No need to interpret complex numbers – just look at the color and know your water quality instantly.","Automatic Temperature Compensation for Accurate, Stable Readings – Built-in ATC ensures precise measurements across varying water temperatures (0-50°C). High-sensitivity probe delivers reliable, repeatable results for TDS, EC, salinity, and hardness whether you're testing cold well water or warm aquarium water. User-friendly design with just a press of a button to power on and measure.","Versatile Use Cases – From Drinking Water to Saltwater Tanks – Test your home tap water, bottled water, well water, purified water, groundwater, seawater, aquaculture systems, and surface water (excluding sewage). Perfect for homeowners, aquarists, RV owners, homesteaders, and anyone serious about water quality."]
