NBL-S-HS 7-in-1 Handheld Portable Soil Tester

The NBL-S-HS 7-in-1 handheld portable soil tester is designed for rapid field checking of seven soil parameters: soil temperature, moisture, electrical conductivity (EC), pH, nitrogen (N), phosphorus (P) and potassium (K).

The system combines a portable handheld meter with a 7-in-1 soil sensor, allowing operators to move between sampling points, view measurements directly on the LCD screen, save measurement records and export stored data to a computer through USB.

This portable soil testing equipment is suitable for farms, greenhouses, irrigation projects, horticulture, field surveys, agricultural service teams and research applications where repeated spot measurements are required. It is intended for field screening and comparative soil monitoring, rather than replacing laboratory chemical analysis.

What Does the 7-in-1 Portable Soil Tester Measure?

The standard 7-in-1 configuration combines seven displayed soil parameters in one field-testing system.

Important: Salinity is not counted as a separate parameter in the standard 7-in-1 configuration above. If soil salinity measurement is also required, select an appropriate 8-in-1 configuration and confirm the exact sensor model before ordering.

Handheld Tester Main Unit Specifications

What Is Included?

A typical 7-in-1 handheld soil-testing set includes the handheld meter, compatible 7-in-1 soil probe, connection cable, USB data cable and portable carrying case. The exact supplied accessories should be confirmed in the quotation.

Portable Soil Testing with Data Storage and USB Export

Unlike a simple soil meter that only displays the current reading, the NBL-S-HS can store measurement records in the handheld unit. Operators can record readings manually or configure automatic interval recording according to the field-testing workflow.

Stored records can be downloaded to a computer through USB using the compatible NiuBoL handheld tester software. This is useful when measurements from multiple plots or sampling points need to be organized and compared after field work.

The exported measurement records are intended for data review and reporting. Internal raw sensor signals should not be assumed to be available unless specifically confirmed for the supplied configuration.

Important Note About Soil NPK Measurements

The N, P and K values provided by this type of integrated soil sensor should be treated as empirical field indicators, not as direct chemical analysis equivalent to laboratory soil testing.

The NPK values are derived from the electrical characteristics of the soil using an empirical relationship. Soil type, moisture, salinity and field conditions can influence the displayed nutrient values. For this reason, NPK readings are more suitable for comparative field screening than for replacing laboratory reference methods.

Soil pH Measurement

The integrated soil pH channel uses an electrode-based measurement method. The probe must make proper contact with the soil for meaningful field readings.

Field pH measurements can be useful for rapid screening and comparison, but they should not automatically be treated as equivalent to a laboratory glass-electrode soil analysis. Projects requiring higher pH accuracy, standardized sample preparation or laboratory traceability should specify those requirements before product selection.

How to Use the Handheld Soil Tester

For repeatable field measurements, use a consistent sampling procedure. Differences in soil contact, sampling depth, moisture condition and measurement location can create differences between readings even when the tester is operating normally.

Key Features

Handheld Soil Tester vs Fixed RS485 Soil Sensor

A portable soil tester and a fixed RS485 soil sensor solve different monitoring problems. Select the format according to whether the project requires mobile spot checks or continuous unattended measurements.

For continuous fixed monitoring, see theNBL-S-TMC-7 7-in-1 RS485 Soil Integrated Sensor.

Which Portable Soil Testing Option Should You Choose?

Portable Soil Tester Applications

The handheld tester is suitable for projects where operators need to move between multiple measurement points rather than leaving a sensor permanently installed in one location.

7-in-1 Handheld Portable Soil Tester FAQ

Q1. What does the 7-in-1 portable soil tester measure?

A1. The standard 7-in-1 configuration measures soil temperature, moisture, electrical conductivity, pH, nitrogen, phosphorus and potassium.

Q2. Does the 7-in-1 tester measure soil salinity?

A2. Salinity is not counted as a separate parameter in the standard seven-parameter configuration described on this page. If salinity is required in addition to temperature, moisture, EC, pH and NPK, select an appropriate 8-in-1 version.

Q3. Are the NPK readings the same as laboratory soil-test results?

A3. No. The NPK values are empirical estimates related to soil electrical characteristics and should be used for field indication and comparative monitoring rather than treated as equivalent to direct laboratory chemical analysis.

Q4. Can the handheld soil tester save measurement data?

A4. Yes. The handheld unit can store up to approximately 20,000 measurement records and supports manual or automatic interval recording.

Q5. Can the data be exported to a computer?

A5. Yes. Stored measurement records can be downloaded through USB using the compatible handheld tester PC software for subsequent review and reporting.

Q6. Does the handheld tester have GPS?

A6. GPS availability should be confirmed for the specific handheld configuration being ordered. If latitude and longitude are required for every sampling point, include this requirement in the inquiry before purchase.

Q7. Is the tester suitable for continuous online monitoring?

A7. The handheld tester is primarily intended for portable spot checking. For continuous measurements at fixed locations, use RS485 soil sensors connected to a data logger or IoT gateway.

Q8. Can it be used directly in field soil?

A8. Yes. Select a representative location, avoid stones and hard objects, and maintain good contact between the probe and the surrounding soil. Use the same sampling method when comparing different locations.

Q9. Can the handheld unit work with other sensors?

A9. The NBL-S-HS platform supports compatible interchangeable sensors depending on the supplied configuration. Confirm the sensor type and interface before ordering additional probes.

Q10. What information is required for a quotation?

A10. Provide the required measurement parameters, quantity, cable length, required accessories, GPS requirement if applicable, destination country and whether PC data export or additional compatible sensors are required.

For quotation and model selection, specify whether you require the 7-in-1 or 8-in-1 soil configuration, quantity, cable length, data-export requirements, GPS requirement if applicable and destination country.

If the project requires laboratory-grade nutrient analysis, continuous unattended monitoring, remote cloud transmission or integration with an existing agricultural IoT platform, include these requirements so the appropriate soil-testing or fixed-monitoring solution can be selected.
