VIVOSUN pH/TDS/EC Meter Combo Kit — 3-in-1 Digital pH Meter, TDS & Soil Moisture/Light Tester with Backlit LCD

The VIVOSUN combo gives gardeners and hydroponic growers three precise handheld instruments: a digital pH meter, a TDS/EC/temperature meter, and a soil moisture/light/pH tester for fast, actionable readings.

If you manage houseplants, a hydroponic system, an aquarium, or a garden bed, consistent water and soil measurements are essential. This VIVOSUN kit groups laboratory-style accuracy and easy-to-read displays into portable tools designed for everyday use. The meters cover key chemistry (pH, TDS, EC, temperature) and physical conditions (soil moisture, light) to help you monitor plant health and water quality without complicated equipment.

How accurate are the pH and TDS/EC readings?

The digital pH meter measures across the full pH range (0.00–14.00) with ±0.1 accuracy and includes one-touch automatic calibration with buffer packs for reliable setup. The TDS/EC meter reads TDS up to 9999 ppm and EC up to 9999 µS/cm with temperature reporting (0.1–80°C / 32–176°F) and automatic temperature compensation to stabilize results.

• pH range: 0.00–14.00, ±0.1 accuracy, one-touch calibration
• TDS range: 0–9999 ppm; EC range: 0–9999 µS/cm
• Temperature: 0.1–80°C (32–176°F), ATC included
• Backlit LCD and hold function for clear, recorded readings

Can I test soil moisture, light and pH with one tool?

The compact soil tester switches between moisture, light and pH modes with a single button so you can evaluate growing conditions at the pot or in-ground quickly. Moisture uses a 1–10 scale, light reads up to 2000 (relative units for bright vs dim), and the soil pH range covers 3.5–8.0 to identify acidic or alkaline conditions.

• Soil moisture scale 1 (dry) to 10 (moist)
• Light intensity scale 0–2000 for assessing exposure
• Soil pH span 3.5–8.0, ideal for most garden plants
• No batteries required for the soil tester—ready to use

How do these meters fit into everyday plant care and hydroponics?

Use the pH and TDS/EC meters to check nutrient strength and water quality before each feeding, and use the soil tester to time watering and confirm light levels. The combination helps you avoid overwatering, nutrient lockout, and imbalanced reservoirs by providing quick diagnostics you can act on.

• Pre-feed checks: measure pH and TDS/EC in nutrient solutions
• Watering decisions: moisture scale prevents over- or under-watering
• Light placement: ensure plants receive adequate intensity
• Portable, fast readings for greenhouse, balcony, or indoor setups

Who is this for? Growers who want a practical, multi-instrument solution to monitor water chemistry and growing conditions will benefit most: hobby gardeners, houseplant enthusiasts, hydroponic operators, aquarists, and anyone testing drinking or pool water affordability. If you need laboratory-level parameters in a portable, easy-to-read package, this VIVOSUN trio supplies the essential measurements without extra bulk or complexity.
