This 7-in-1 digital soil tester combines soil pH, moisture, fertility and soil temperature with light, air temperature and humidity on one backlit display. It is designed for routine monitoring in gardens, containers, greenhouses and other growing areas.
Soil pH and moisture are measured directly, while the fertility value should be used as a directional indicator rather than an exact nutrient concentration. Interpret each reading according to the plant, growing medium and conditions you are monitoring.
pH: Compare the reading with the preferred range for the plant you are growing.
Moisture: Use repeated readings in the active root zone to understand how the soil dries between waterings.
Light and humidity: Compare environmental conditions over time and interpret them according to the plant species and growing location.
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?
Insert the probe into a representative part of the active root zone according to the product instructions. Avoid forcing it against stones, thick roots or other hard material. Use a similar testing depth when comparing readings over time.

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 tester combines seven soil and environmental parameters in one device: soil pH, fertility, moisture, soil temperature, light intensity, air humidity and ambient temperature. These readings provide practical context for routine plant monitoring without treating one measurement as a complete diagnosis.
The large backlit LCD and one-button controls make it easy to view multiple soil and environmental readings in one place. The probe is designed for routine monitoring of soil pH, moisture, fertility and temperature, while the device also displays light, air temperature and humidity.
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.
Follow the testing method designed for this meter. Insert the probe carefully into suitable soil as instructed, avoid stones and thick roots, and allow the reading to stabilize. When comparing results over time, use similar soil conditions and testing depth.
No. Different plants prefer different soil pH conditions. Compare the reading with a reliable recommendation for the specific plant or crop rather than using one universal target for every garden.
Lime may be used to raise soil pH and elemental sulfur may be used to lower it, but the appropriate amendment and rate depend on the soil, target pH and plant. For a substantial pH correction, confirm the result with a laboratory soil test or regional Extension recommendation before applying an amendment.
Test when you need to establish a baseline, investigate a plant problem or monitor a change in soil conditions. When comparing readings over time, use the same testing method and similar conditions rather than relying on one universal testing schedule.
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.
Compare soil pH, moisture, fertility, temperature and surrounding environmental conditions using one device. Use repeated readings to identify trends rather than treating one measurement as a complete diagnosis.
The compact handheld design and soil probe are built for routine use in gardens, containers, greenhouses and other growing areas.
The backlit display and simple controls make it easy to view multiple soil and environmental parameters without requiring a mobile app.
