8-in-1 Soil Sensor Portable Type-C/USB Soil Multi-Parameter Tester & Analyzer Product Overview: Definition & Core Value

What is the NiuBoL Soil Multi-Parameter Tester & Analyzer?

The NiuBoL 8-in-1 Soil Sensor Soil Multi-Parameter Analyzer is a high-precision, multifunctional portable device specifically designed for soil environmental monitoring. It can be connected to the user’s Android or HarmonyOS smartphone (requires compatibility with version 4.3 and below) to measure eight key soil parameters in real time and rapidly:

• Soil temperature & Soil moisture (volumetric water content) & Soil EC (electrical conductivity) & Soil salinity &NPK

With its excellent measurement accuracy, good stability, and simple operation, this product has become an ideal tool in the fields of water-fertilizer integration, environmental monitoring, and scientific research.

Innovative Technology: In-Depth Working Principle Analysis

Multi-Parameter Integrated Measurement Principle

This analyzer adopts integrated sensor technology to achieve multi-parameter measurement:

Temperature & Moisture: Temperature is typically measured using thermistors or semiconductor chips; moisture is measured using Frequency Domain Reflectometry (FDR) or Time Domain Reflectometry (TDR) principles by detecting the soil dielectric constant, thereby calculating the volumetric water content.

EC & Salinity: Measures the electrical conductivity of the soil solution to reflect the total concentration of soluble salt ions. Soil salinity value (mg/L) is closely related to electrical conductivity (μS/cm) and can usually be converted.

Nitrogen, Phosphorus, Potassium (NPK) Content: 【Important Note】 NiuBoL soil NPK sensor essentially measures soil electrical conductivity. The manufacturer obtains an empirical, theoretical value by multiplying the measured conductivity value by coefficients based on nitrogen, phosphorus, and potassium content in conventional soil. Due to differences in field soil and environment, the NPK values provided by this sensor are for guidance reference only, not precise laboratory measured values.

pH Value: Uses a dedicated pH composite electrode to measure the hydrogen ion concentration in the soil solution via the potential difference method, thereby obtaining the soil acidity/alkalinity.

Customer FAQ

Q: Which phone systems are compatible with the NiuBoL Soil Multi-Parameter Analyzer?
A: Compatible with Android and HarmonyOS 4.3 and below smartphones. Not compatible with Apple iOS devices or HarmonyOS 5.0 and above.

Q: What soil parameters can this device measure?
A: One-stop measurement of eight parameters: soil temperature, soil moisture, soil EC, soil salinity, available nitrogen, available phosphorus, available potassium, and soil pH.

Q: Why no response after connecting the device to the phone?
A: Most common cause is disabled OTG function. Go to phone settings, search for 'OTG' and enable it manually.

Q: Are NPK measurement values completely consistent with laboratory data?
A: Not completely. The sensor’s NPK values are theoretical reference values calculated from soil conductivity using empirical coefficients. Due to complex soil composition, they are mainly used for rapid, on-site trend judgment, not precise laboratory analysis.

Q: How to handle if my phone cannot install the APP?
A: Some domestic phones (Huawei, Xiaomi, OPPO, VIVO) block non-official installations. Disable “Pure Mode” or “Security Guardian” or allow “one-time installation authorization” according to the model.

Q: Which languages does the APP support?
A: Supports switching between Chinese and English.

Q: How deep does the probe need to be inserted during measurement?
A: To ensure measurement accuracy, the sensor probe must be fully inserted into the soil to be measured.

Q: Can the sensor be buried in soil for long-term use?
A: Yes. The sensor supports long-term burial monitoring, but avoid chemical corrosion and high-heat environments.

Q: Can APP data be exported?
A: Yes, the APP supports data storage and export as Excel files.

Q: What is the warranty period?
A: The product comes with a one-year warranty. Free repair or replacement for faults caused by sensor quality issues within 12 months from shipment (excluding man-made damage excluded).
