Advantages and Usage of Soil pH Sensor

Soil pH is one of the most important factors affecting plant growth and crop yield. Accurate soil pH measurement is crucial for agricultural irrigation, flower horticulture, grass pasture, soil research and other fields. However, there are many problems with traditional soil pH measurement methods, such as the need to equip professional display meters, cumbersome calibration, difficult integration, high power consumption, expensive, and difficult to carry, etc. The NBL-S-PH Soil pH Sensor is an innovative agro-technology product, which cleverly solves the difficulties faced by the traditional soil pH testing.

NBL-S-PH soil pH sensor has many advantages:

1. Wide measuring range: the sensor is able to measure the soil pH value in the range of 0-14pH, which is suitable for various soil types.

2. High accuracy: the sensor's accuracy reaches ±0.1pH, ensuring the reliability of the measurement results.

3. High resolution: the sensor has a resolution of 0.01pH, which can provide finer measurement data.

4. Flexible power supply mode: the sensor supports DC 12V-24V power supply mode, adapting to various voltage environments.

5. Various output forms: the sensor provides voltage (0-5V), current (4-20mA) and RS485 and other output forms, which is convenient for users to choose the appropriate output method according to their needs.

6. High integration: the sensor has a high degree of integration, reducing the complexity of the device, easy to install and use.

7. Low power consumption: the sensor has low power consumption, which is conducive to energy saving.

8. affordable: compared with traditional soil PH value detection equipment, the sensor price is more affordable, for the majority of users to accept.

9. easy to carry: the sensor is compact, light weight, easy to carry and field operation.

NBL-S-PH Using soil pH sensor method 

Firstly, take out the protective cover on the sensor, fix the filter tank to the sensor and wrap the filter mesh around the filter tank with the included tie to prevent direct contact between the soil and the probe.

Then, insert the probe section vertically into the soil to a depth that covers the filter mesh. Pour a certain amount of water around the soil to be measured and wait a few minutes for the water to soak into the probe to read the soil pH on the instrument.

To ensure accurate measurements, the user can calibrate with the supplied pH reagent. In addition, it is also necessary to pay attention to some usage matters, such as avoiding air bubbles between the measuring cells, checking whether the package is intact, and checking the product model number. Meanwhile, the sensor probe should be cleaned regularly to maintain its good measurement performance.

In terms of maintenance, it is necessary to keep the input end of the instrument dry and clean, and avoid prolonged immersion in protein solution and acidic fluoride solution. The electrodes should be calibrated and cleaned regularly to ensure the accuracy of the measurement. In addition, the transmitter should be placed in a dry environment or control box to prevent instrument leakage or measurement errors caused by splashing water droplets or moisture.

In conclusion, NBL-S-PH soil pH sensor is a revolutionary solution for soil acidity and alkalinity measurement. It not only solves many problems of traditional soil pH measurement methods, but also provides a fast, accurate and convenient means of soil pH measurement for agriculture, horticulture, grass pasture, soil research and other fields. With the continuous progress of soil pH measurement technology, we have reason to believe that NBL-S-PH sensor will be more widely used in the future.
