About This

• LKBird Exclusive 9-in-1 Water Tester: All-in-One Detection for Turbidity, Hardness, TDS, EC, Salinity, TOC, COD & UV Absorbance with Unique Dual-Core Advantages in Turbidity (NTU) and Water Hardness Testing. Whether checking excessive suspended particles via precise NTU readings or assessing hard water scale risks, this all-in-one device eliminates the need for multiple testers.
• Smart App Connectivity: Equipped with seamless Bluetooth connectivity, simply pair it with our dedicated "Kactoily" App to sync test results to your phone in real time—eliminating the hassle and errors of manual logging. Enjoy permanent storage of historical data, auto-generated trend charts, and multi-scenario data classification and tagging. Whether at home or on the go, easily access past records to gain precise insights for improving water quality, making household health management effortless and worry-free.
• Lab-Grade Precision Testing: Equipped with imported high-sensitivity sensors and dual optical-electrochemical modules, it uses 90° scattered light for turbidity testing and precisely quantifies calcium/magnesium ions for hardness detection. With ≤±2% measurement error and 0.01-unit resolution, its accuracy matches professional lab equipment. The built-in Automatic Temperature Compensation (ATC) ensures stable readings from 0-60°C, making TDS meter ideal for both household and professional use.
• Ultra-Simple Operation & Durable Design: Auto-calibrates on startup—no complicated setup. Immerse the probe in water for just 3 seconds to get stable, accurate readings. The backlit LCD screen ensures clear visibility even in dim environments. With an IP67 waterproof and dustproof rating, it withstands accidental water submersion. Weighing only 90g, its compact pen-style design fits easily into pockets or toolboxes, making it the ideal digital water tester for home, fieldwork, and travel—reliable testing anytime, anywhere.
• Full-Scenario Versatility – Beyond an Ordinary Water Tester: Ideal for testing drinking and purified water at home, monitoring aquariums and fish tanks, checking hydroponic nutrient solutions, and screening water quality while traveling. In industrial settings, it assists with boiler and cooling water hardness monitoring to help identify scaling risks. Also suitable for preliminary outdoor water source screening and basic laboratory testing. One device, multiple applications!
• 【Before You Buy — Please Check Your Use Case】This water tester is a great fit if you want a quick overview of your everyday water. It is NOT the right tool if you need: (1) pH measurement — this model does not measure pH; (2) a numerical hardness value in gpg, mg/L or °dH for setting up a water softener — hardness is shown as a 4-level indication only; (3) salinity testing for a saltwater pool or aquarium — please use a dedicated salt/salinity tester; (4) certified results for regulatory, industrial or laboratory reporting. If you're unsure, message us before ordering and we'll tell you honestly whether it fits.
