Frequently Asked Questions

Q: What nutrients does the Soil NPK Analyzer Meter measure?

A: The ATUOTIN Soil NPK Analyzer measures the three primary macronutrients essential for plant growth: Nitrogen (N), Phosphorus (P), and Potassium (K). All three are tested in the 0–1999 mg/kg range, giving you a comprehensive picture of your soil's fertility and nutrient balance.

Q: Do I need batteries, and how do I use the dual-probe soil tester?

A: Yes, the meter requires 3 × AAA batteries (not included). To use, insert the dual metal probes into the soil at approximately a 45° angle to the recommended depth. The LCD screen will display your NPK readings within seconds. The device auto-shuts off after 30 seconds of inactivity to preserve battery life.

Q: Is this soil nutrient detector suitable for both indoor potted plants and outdoor farmland?

A: Absolutely. The Soil NPK Analyzer Meter is designed for versatile use — it works equally well for indoor potted plants and flowers as it does for outdoor gardens, lawns, vegetable patches, orchards, greenhouses, and large agricultural fields.

Q: How accurate is the NPK reading, and what is the measurement range?

A: The meter provides high-precision readings across a wide 0–1999 mg/kg range, suitable for most soil types encountered in home gardening and professional agriculture. The 170 mm sensitive dual-needle probe design ensures consistent contact with the soil for reliable results.
