Digital Drinking Water Tester — Lab-Grade 4-in-1 TOC, COD, TDS & Temp for Organic Contamination (Algae, VOCs, Chemicals) | Well, Tap, Aquarium & Outdoor Water Quality $$Tools

Comprehensive screening in one handheld device — this pocket-sized water tester measures TOC (Total Organic Carbon), COD (Chemical Oxygen Demand), TDS and Temp to guide a tiered testing approach when laboratory panels feel overwhelming or costly. It reports both inorganic (TDS) and, uniquely for consumers, organic contamination (pathogens, VOCs/SOC, home-use chemicals and algae). This is the first and so far only consumer device on the market that delivers instant organic contamination results. Why TOC and COD matter more than TDS alone — TOC and COD quantify organic pollution in drinking water: natural organics such as algae and microbiological contaminants, plus synthetic or volatile organics (SOC / VOC) like pesticides, cleaners and THMS. TOC also reacts with chlorine to create carcinogenic disinfection byproducts (DBP), so monitoring and controlling TOC before chlorinating well water is important. Instant, lab-grade readings — TOC and COD traditionally required professional lab analysis or bulky analyzers. This tester uses innovative UV spectral technology to provide lab-grade results in seconds without expensive, inconvenient lab testing. Pairs with water treatment systems — use this tester to demonstrate water quality changes before and after filtration, when replacing filter cartridges, or when evaluating a new pitcher or dispenser. It is also useful for detecting biofouling in RO systems. Portable verification anywhere — designed for easy field use, the unit fits in your pocket and is suitable for water professionals as a rapid screening tool or for outdoor expeditions where drinking water comes from rivers or lakes. Maintenance and use notes — recalibrate the device using distilled water. AVOID BUBBLE ON THE PROBE HEAD IN BOTH CALIBRATION AND TESTING, BY SHAKING THE TESTER GENTLY WHILE THE HEAD IS IN SAMPLE WATER.
