Vivosun 3-in-1 Water & Soil Testing Combo
Nutrient lockout, pH drift, and over-watering are hard to catch by eye. By the time leaves yellow or curl, the problem has usually been building for days. The Vivosun Water & Soil Testing Combo gives you three dedicated meters in one kit so you can check both your water and your root zone before symptoms appear. The kit includes a digital pH meter with ±0.1 accuracy, a 4-mode TDS/EC/temperature tester, and a battery-free analog soil tester.
The Vivosun pH tester reads 0.00–14.00 pH and calibrates with one touch using the included buffer powder packs. The 3-in-1 TDS tester measures total dissolved solids (0–9999 ppm) and electrical conductivity (0–9999 µS/cm) with ±5% accuracy. It shows water temperature on the same screen, and you can cycle through four display modes to read ppm or µS/cm alongside °C or °F. Both digital testers use large backlit LCD screens that stay readable in dim grow rooms. The TDS tester's HOLD button locks a reading on screen so you can record it.
For soil growers, the 3-in-1 soil tester slides between moisture, pH, and light modes. Its color-coded dial shows at a glance whether your medium is dry, moist, or wet, and whether it's acidic or alkaline. The dual 7.8″ probes reach into the root zone, and the tester needs no battery. The Vivosun combo covers hydroponic reservoirs, soil beds, RO systems, aquariums, pools, spas, and household water checks.
