NiuBoL Multi-Parameter Portable Soil Tester Solution

In scenarios such as precision agriculture, water-saving irrigation, and rapid soil diagnosis, portable, stable, and digitally recordable soil testing equipment is gradually replacing traditional manual sampling and laboratory analysis methods.

The Soil Tester Portable USB Type-C 8 in 1 Soil Sensor launched by NiuBoL enables rapid measurement and data management of key soil parameters through direct phone connection and a free APP, providing a more efficient tool for agricultural production and scientific research monitoring.

Soil Tester Portable USB Type-C 8 in 1 Soil Sensor Product Overview

The NiuBoL portable 8-in-1 soil sensor adopts a USB Type-C interface, which can be directly connected to Android and HarmonyOS (4.3 and below) system phones without the need for additional power supply or acquisition devices.

After installing the APP, it can measure and display in real time 8 key parameters: soil temperature, moisture, electrical conductivity (EC), salinity, available nitrogen, available phosphorus, available potassium, and pH value.

The device features an overall sealed structure and stainless steel probe design, balancing on-site portability with long-term burial stability, suitable for rapid field testing and short-term monitoring applications.

Soil Tester Portable USB Type-C 8 in 1 Soil Sensor Working Principle Explanation (Factual)

Explanation Regarding NPK Measurement

This soil NPK sensor does not directly chemically detect nitrogen, phosphorus, and potassium content. Instead, it measures soil electrical conductivity (EC) and then uses empirical models and coefficients to derive estimated values for nitrogen, phosphorus, and potassium.

This measurement method is suitable for:

  • Judging soil fertility trends

  • Before-and-after comparisons within the same plot

  • Evaluating changes before and after fertilization

However, due to significant differences in soil structure, organic matter content, and salinity across different regions, the results cannot be fully equated to laboratory chemical analysis values. For scientific research or precise quantitative needs, it is still recommended to combine with laboratory testing.

Explanation of pH Measurement Principle

This pH sensor uses the electrode method for measurement:

  • After the probe is inserted into the soil

  • The zinc electrode reacts with hydrogen ions in the soil

  • Generating a potential difference proportional to the hydrogen ion concentration

  • From this, the soil pH (acidity and alkalinity) is calculated

It should be noted that this type of electrode-based soil pH sensor has certain accuracy limitations in complex soil environments and is suitable for rapid on-site judgment of pH trends.
If extremely high pH accuracy is required (such as for scientific research or standardized testing), glass electrode pH sensors are generally recommended.

Free Android APP Function Introduction

The accompanying free mobile APP is an important component of this device. Core functions include:

  • Real-time data display (8 parameters displayed synchronously)

  • Parameter calibration and correction settings

  • Historical data storage and query

  • Data curve visualization

  • One-click export to Excel file

  • Chinese/English interface switching

  • APP automatic online upgrade

Data collection, management, and export can be completed directly through the phone, significantly reducing on-site testing and post-processing costs.

Device Usage Method

  1. Install the APP on an Android or HarmonyOS (4.3 and below) system phone

  2. Insert the sensor's USB Type-C connector into the phone's charging port

  3. The APP recognizes the device and successfully connects

  4. Fully insert the stainless steel probe into the soil to be tested or bury it for long-term use

  5. Wait for the data to stabilize, then read and record the results

The entire process requires no additional power supply or complex settings, making it suitable for rapid on-site operations.

Soil Tester Portable USB Type-C 8 in 1 Soil Sensor Application Scenarios

The NiuBoL portable 8-in-1 soil tester is widely applicable to:

  • Water-saving agriculture and precision irrigation management

  • Greenhouses and protected agriculture

  • Flower, vegetable, and cash crop planting

  • Grassland, pasture, and horticultural management

  • Rapid soil testing and on-site diagnosis

  • Plant cultivation and teaching experiments

  • Environmental monitoring and agricultural scientific research support

It is particularly suitable for application scenarios that require quick decision-making, data recording, and comparative analysis.

System Compatibility Description

Supported systems: Android / HarmonyOS 4.3 and below
Unsupported systems: Apple iOS, HarmonyOS 5.0 and above
Please confirm the phone system version in advance during model selection to ensure normal device operation.

FAQ:

Q1: Can this soil tester be buried in the soil for a long time?
Yes. The probe is made of corrosion-resistant materials and is suitable for short-term or periodic burial, but for long-term continuous monitoring, it is recommended to periodically remove and inspect it.

Q2: Can the NPK values be used as a basis for fertilization?
It can be used as a reference and trend judgment tool, but it is not recommended to completely replace laboratory analysis data.

Q3: Is additional power supply required?
No, the device is powered directly by the phone's USB Type-C interface.

Q4: Does it support data upload to the cloud?
The current version mainly supports local storage and Excel export, facilitating users to manage and analyze data themselves.

Summary

The NiuBoL Soil Tester Portable USB Type-C 8 in 1 Soil Sensor is a multi-parameter soil testing tool designed for rapid on-site detection and digital management.

It does not aim for laboratory-grade absolute accuracy but emphasizes portability, stability, data visualization, and practical value. It is very suitable for agricultural production, technical services, project evaluation, teaching, and scientific research scenarios.

For users who need to quickly understand soil conditions, optimize irrigation and fertilization decisions, this is a cost-effective, highly efficient, and low-barrier solution.
