Curious about what's really in your tap water? This TDS water electrolyzer lets you test water purity at home. It uses electrolysis to show impurities – just plug into 220V, immerse the electrodes in water, and watch for color changes (cloudiness, particles). Measuring range: 50-200 mg/L. Comes with an 80cm (31.5\) cable. Made from ABS and aluminum-iron materials. Compatible with DJQ-1 model. It's a simple, visual way to check for dissolved solids, though not a lab-grade device. Great for checking filtered water, well water, or aquarium water. Brand new, unbranded. Keep your family informed about water quality. Note: This tool indicates TDS levels via electrolysis, not digital readout. A handy gadget for health-conscious households, gardeners, or hobbyists. Test, see, and decide if you need better filtration!
