This 7-in-1 soil tester reads soil pH, moisture, fertility, and temperature, plus light, air temperature, and humidity—a rounded read on both your soil and the environment around your plants, all on one backlit screen. Push it into moist soil and check the values.
The pH and moisture are measured directly. Read pH as a direction, aiming for 6.0 to 7.0 for most plants. The fertility figure is a directional gauge of overall nutrient level, useful for spotting thin or salty soil, not an exact nutrient number.
Want actual N, P, K instead of overall fertility? See our NPK soil tester; for precise salt, a soil EC meter.
Yieryi has built pH, EC, and TDS meters for more than ten years. More parameters mean more convenience; we are honest about which are measured and which are a directional guide.
Does it measure NPK?
It reads overall fertility as a direction, not individual N, P, K. For nutrients, use an NPK tester.
Does it need batteries?
Yes—it runs on 3 AAA batteries (not included).
Where should I insert it?
About 3 to 5 inches into moist soil at root depth; wipe the probe clean after each use.

How to use it
Where it works best
Gardens, greenhouses, indoor plants, and farms—for gardeners who want soil and environment in one tool.
The rapid test ph meter measures seven key parameters—soil pH, fertility, moisture, light intensity, soil temperature, air humidity, and ambient temperature—providing a complete picture of growing conditions. Ideal for Landscape hobbyists and Plant enthusiasts to scientifically observe plant growth environments
This multi-functional ph meter for plants comes equipped with a high-precision probe and a large LCD display, allowing you to quickly and accurately analyze soil moisture, temperature, pH, and nutrient levels. The backlit screen ensures clear data visibility, whether it's day or night.
The compact and lightweight design, combined with a corrosion-resistant probe, ensures portability and long-lasting performance in various environments.
Soil pH affects the availability of nutrients to plants. Different plants thrive in different pH ranges. If the pH is too high or too low, plants may not be able to absorb essential nutrients, leading to poor growth or even death.
You can test soil pH using a pH meter by creating a soil slurry with distilled water. Mix the soil and water, let it settle, and then insert the pH meter electrode into the liquid.
Most plants prefer a slightly acidic to neutral pH range of 6.0-7.0. However, some plants, like blueberries and azaleas, prefer more acidic soil.
You can raise the pH of acidic soil by adding lime or wood ash. To lower the pH of alkaline soil, you can add sulfur or peat moss.
It's recommended to test your soil pH at least once a year, preferably in the spring or fall. You may need to test more frequently if you are experiencing plant growth problems or if you have recently amended your soil.
Soil pH changes over time. Influencing factors include rainfall, fertilization, organic matter decomposition, and plant root activity. Regularly testing soil pH helps detect problems in time and make adjustments.
Ensure precise and consistent pH measurements for reliable results in every application, from water testing to agriculture.
Built with high-quality materials, our pH meters are designed to withstand rigorous use, offering long-lasting performance you can trust.
Featuring intuitive controls and a clear display, our pH meters make testing effortless, even for beginners.
