This 6-in-1 soil tester reads soil pH, EC, moisture, fertility, light, and temperature on one backlit screen, so you get a rounded read on your soil from a single probe. Push it into moist soil and the display shows pH, EC in mS, temperature, and fertility at once, with light and moisture indicators.
What sets this one apart from most 6-in-1 meters is a calibration button. The pH, EC, moisture, and temperature are measured directly, and because you can calibrate the pH against a known reference, its pH read is more trustworthy than fixed, factory-only meters. The fertility figure is a directional gauge based on conductivity—useful for spotting thin or salty soil, not an exact nutrient number.

Yieryi has built pH, EC, and TDS meters for more than ten years. A 6-in-1 trades a little precision for convenience; the calibration button narrows that gap on pH, and we are honest about which readings are measured and which are a directional guide.
Can I calibrate it?
Yes—it has a CAL button, so you can calibrate the pH against a known reference for a more reliable read. It comes factory-calibrated, so recalibration is optional and only needed for extra precision.
Does the fertility reading show NPK?
No—it shows overall fertility as a conductivity-based direction, not individual N, P, or K.
Does it need an app or batteries?
No app—it reads on its own LCD. It runs on AAA batteries.

How to use it
Where it works best
Indoor pots, home gardens, greenhouses, and lawns. Best in common garden and potting soil; avoid hard, rocky, or purely sandy ground, and never immerse the head in water.
Overwatering is one of the top reasons plants die, while underwatering leaves them dry and stressed. This moisture meter helps you check soil wetness instantly so you’ll know exactly when to water. For healthy growth, most plants prefer soil moisture in the 40–60% range, which keeps roots hydrated without drowning them. Say goodbye to guessing games and protect your plants from both drought stress and root rot.
If your plants look weak even with regular watering, the problem is often soil imbalance. This smart soil pH tester quickly detects whether your soil is too acidic or alkaline, helping you prevent nutrient lockout and stunted growth. Most flowers, vegetables, and herbs grow best at a pH of 6.0–7.0, where nutrients are most available. With instant feedback, you can adjust your soil conditions and keep roots healthy from the start.
Sunlight confusion is a major issue for plant lovers—too little light slows growth, while too much light burns leaves. This digital light sensor takes the guesswork out by showing how much light your plants actually get each day. For most houseplants and crops, the ideal exposure is 6–8 hours of moderate light daily, enough to fuel photosynthesis without causing stress. Now you can move your pots with confidence and stop worrying about poor blooms or leaf damage.
Uneven growth and pale leaves often point to low soil fertility. This fertility meter helps you track nutrient levels so you know exactly when to enrich your soil. Plants typically thrive with a fertility level between 40–70%, which ensures steady access to key nutrients without over-fertilizing. By keeping soil in this range, you’ll enjoy stronger stems, greener leaves, and more productive harvests season after season.
Many gardeners struggle with weak crops because of poor soil conductivity, which affects how well roots absorb nutrients. This EC tester measures soil salinity and conductivity, making it easy to maintain the right environment. Most vegetables and fruits grow best with a soil EC between 1.0–2.5 mS/cm, where minerals are balanced and growth is optimized. With the right EC levels, you can double plant growth and prevent common nutrient issues.
Easily keep your favorite indoor plants like fiddle leaf figs, pothos, and succulents healthy by checking soil moisture and light levels. Prevent root rot or leaf drop with accurate readings.
Grow fresh tomatoes, peppers, and herbs right on your balcony or backyard. Optimize soil pH, nutrients, and conductivity to boost yield and flavor.
Achieve greener, thicker lawns and vibrant outdoor plants. Quickly balance soil acidity and moisture to prevent yellow patches or uneven growth.
Soil pH determines how well plants absorb nutrients. Most vegetables and flowers grow best at a pH level between 6.0 and 7.0, which prevents nutrient deficiencies and promotes stronger root systems.
For best results, check your soil once or twice a week during the growing season, and always before watering, fertilizing, or changing plant placement. Regular monitoring prevents overwatering, over-fertilizing, and other common mistakes.
Yes! The soil tester works for indoor houseplants, balcony gardens, outdoor lawns, greenhouses, and even hydroponics systems. It’s versatile enough for any growing setup.
Most plants prefer soil moisture in the 40–60% range. Too little water causes stress and leaf drop, while too much water can lead to root rot. The tester helps you water at the right time.
The soil ph meter has been calibrated by the factory, and there is no need to recalibrate before using it. Can be recalibrated if great precision is required.
Yes, the digital soil tester requires batteries (usually AAA). Once inserted, it provides accurate readings on the backlit screen for easy monitoring even in low light conditions.
