Is your garden reaching its full potential, or are you just hoping for the best? Most plant problems—yellowing leaves, stunted growth, or poor yields—start beneath the surface.
The YIERYI 6-in-1 Professional Soil Tester gives you a "window" into your soil. By measuring Nitrogen, Phosphorus, and Potassium (NPK) alongside moisture and temperature, you can feed your plants exactly what they need, when they need it. No more over-fertilizing. No more guesswork.
Complete Nutrient Analysis (NPK): Instantly track the three pillars of plant health (Nitrogen, Phosphorus, and Potassium) to ensure lush leaves and vibrant blooms.
Precision Dual-Probe Tech: Unlike cheap single-probe meters, our dual-needle design provides laboratory-grade accuracy in seconds.
The 90° Advantage: Tired of bending down to read the screen? Our display rotates 90 degrees, making it easy to check your soil from any angle.
Smart Nutrient Grading: The built-in grading system tells you if your soil is "Deficient" or "Rich," so you know exactly when to reach for the fertilizer.
Built for Real Life: Waterproof probes and a durable ABS body mean this tool is ready for the backyard, the greenhouse, or the indoor potting bench.

This comprehensive analyzer provides the precise data support needed for thriving balconies and lush greenhouses. By monitoring real-time fertility levels (us/cm), you can maintain the perfect environment for demanding crops like tomatoes, ensuring a vibrant harvest instead of disappointing, weak yields.
Simplify your plant care routine by eliminating the need for multiple tools; this 6-in-1 device tracks everything from root-zone temperature to precise Nitrogen, Phosphorus, and Potassium (NPK) ranges. Keep your soil humidity between 40-70% and temperature within 15-25°C (59-77°F) for optimal photosynthesis, effectively preventing common issues like root rot and heat stress.
From indoor potted plants to outdoor orchards and professional greenhouses, this compact tester solves the challenge of maintaining consistent soil quality across different environments. Use it to ensure your garden maintains a Phosphorus level of 60-100mg/kg, the sweet spot for robust root development and disease resistance in any agricultural or gardening scenario.
For accurate data, ensure the soil is slightly moist (ideally 40-70% humidity) so the dual probes can establish a proper electrical connection. Also, avoid testing in loose media like pure coconut fiber or sandy soil, which do not hold nutrients well enough for a standard reading.
Your NPK levels into five clear grades, from "Extremely Deficient" to "High," ensuring you never burn your plants with excess nutrients again. For high-yield cultivated soil, aim for a Nitrogen balance of 150-200mg/kg to prevent the stunted growth and yellowing leaves that plague most home gardeners.
No calibration is necessary. Your 6-in-1 Soil Tester is professionally calibrated at the factory to ensure high-precision accuracy right out of the box. You can start monitoring your soil NPK and fertility levels immediately without any complex setup.
This usually happens if the soil is too dry or unsuitable. For accurate data, ensure the soil is slightly moist (ideally 40-70% humidity) so the dual probes can establish a proper electrical connection. Also, avoid testing in loose media like pure coconut fiber or sandy soil, which do not hold nutrients well enough for a standard reading.
No. This device is specifically engineered for natural, organic, and mixed plant soils. Inserting the probes into liquids or pure water will result in inaccurate readings and may shorten the lifespan of the high-sensitivity dual needles.
For the most reliable NPK and moisture data, insert the dual stainless steel probes approximately 2/3 of the way (about 8-12cm) into the soil. This ensures the sensors are measuring the "root zone" where your plants actually absorb nutrients.
The tester provides real-time mg/kg data. For most thriving gardens, you want to see a Nitrogen (N) level of 150-200mg/kg and Phosphorus (P) of 60-100mg/kg. If your reading falls below these ranges, our built-in Nutrient Grading Scale will alert you that your soil is "Deficient," signaling it's time to fertilize.
