NiuBoL Portable 8 IN1 Integrated Soil Tester Sensor is a portable soil multi-parameter tester designed for rapid on-site detection needs. The sensor uses a USB Type-C interface, no external power supply or data collector required, just plug it into a mobile phone to read data, truly achieving "plug and measure".
Based on the FDR (Frequency Domain Reflectometry) principle, this device excels in stability, repeatability, and on-site adaptability. It can simultaneously measure 8 key soil parameters, providing intuitive and referenceable data support for agricultural production, scientific research experiments, and environmental monitoring.

No host, no acquisition box, single person can complete on-site testing
Suitable for mobile scenarios such as fields, greenhouses, experimental plots
Reduces equipment investment cost and operation complexity
Strong versatility, compatible with Android and HarmonyOS mobile phones
Data and power supply integration, no battery maintenance required
Stable connection, strong anti-interference ability
More suitable for mobile data acquisition and management
After inserting the sensor into the mobile phone, data can be displayed in real time through the free APP, greatly shortening the time chain from testing to decision-making.
Measurement Principle: FDR Frequency Domain Reflectometry Technology
Probe Material: 316L Stainless Steel
Encapsulation Method: Epoxy Resin Overall Sealing
Protection Level: IP68, suitable for long-term insertion in soil
Output Method: USB Type-C (direct connection to mobile phone)
This structural design balances on-site durability and measurement stability, suitable for various complex soil environments.

| Measurement Parameter | Range | Accuracy | Resolution |
|---|---|---|---|
| Soil Temperature | -40 ~ 80 ℃ | ±0.3 ℃ | 0.1 ℃ |
| Soil Moisture | 0 ~ 100 % (m³/m³) | ±2 % | 0.1 % |
| Soil EC | 0 ~ 20000 μS/cm | ±3 % | 1 μS/cm |
| Soil Salinity | 0 ~ 20000 mg/L | ±3 % | 1 mg/L |
| Soil Available Nitrogen | 0 ~ 1999 mg/kg | ±3 % | 1 mg/kg |
| Soil Available Phosphorus | 0 ~ 1999 mg/kg | ±3 % | 1 mg/kg |
| Soil Available Potassium | 0 ~ 1999 mg/kg | ±3 % | 1 mg/kg |
| Soil pH Value | 3 ~ 10 | ±0.2 | 0.01 |
Directly affects seed germination, root growth, and microbial activity. It is an important indicator for judging the appropriate sowing period and growth status of crops.
Used to evaluate soil moisture status, it is the core basis for water-saving irrigation and precision irrigation decisions, avoiding over-irrigation or water shortage.
Reflects the overall level of soluble salt ions in the soil, can be used to judge fertilization intensity and salt accumulation risk.
Excessive salinity inhibits crop water absorption capacity. This parameter is particularly critical for saline-alkali land improvement and irrigation management.
Closely related to crop leaf growth and yield, suitable for rapid assessment of nitrogen fertilizer supply level.
Affects root development and flower/fruit formation, an important reference for judging base fertilizer and topdressing strategies.
Related to crop stress resistance and quality, suitable for management of cash crops, fruits, and vegetables.
Determines nutrient availability and microbial activity, an important basic parameter for fertilization schemes and soil improvement.

Soil NPK values are converted based on soil electrical conductivity and are empirical/theoretical reference values, not equivalent to laboratory chemical analysis results. Suitable for trend judgment, relative comparison, and rapid on-site evaluation.
Adopts electrode method, which generates potential difference through the reaction between the electrode and hydrogen ions in the soil, thereby calculating soil acidity and alkalinity.
