The Best Soil pH sensor


Only when the soil pH value is about 6.5, the absorption and utilization of nutrient elements are the highest, which is also the most beneficial to the growth and development of crops. Therefore, the role of soil pH sensor is indispensable, so how should we choose this kind of equipment?

Pay attention to the measurement accuracy of the soil pH sensor

Measurement errors will inevitably occur during the measurement process. In order to make the measurement results accurate and reliable, it is necessary to minimize errors and select products with high measurement accuracy.

Pay attention to the sensitivity of the soil pH sensor

Sensitivity is a degree of change in response amount, naturally the higher the better. Sensitivity is related to the sensor. It is best to use imported low-power MCUs and high-quality operational amplifiers to ensure that the sensor has low power consumption, high sensitivity, and stable signal transmission.

Pay attention to the material quality of the soil pH sensor

The quality of the material is one of the guarantees for the service life of the soil pH sensor. The strict manufacturing process is adopted to carry out the waterproof and dustproof treatment on the whole body, which can ensure the stable monitoring of the components. How to distinguish the quality of the material?

For example, it is best to use high-density epoxy resin for high-temperature vacuum filling between the probe and the body, which can prevent moisture from entering the body to a large extent, and the sealing performance will be better. The electrode is also very important. The electrode is made of specially processed alloy material so that it can withstand a strong external impact and is not easily damaged.

Pay attention to the protection level of the soil pH sensor

IP is the abbreviation of Ingress Protection, that is, protection level. The IP protection level system provides a way to classify products based on the degree of dust, water, and collision resistance of electrical equipment and packaging. It is usually expressed by two numbers followed by IP. The numbers are used to clarify the protection level.

The first number indicates the level of protection against dust and foreign objects. The second number indicates the degree of airtightness of the appliance against moisture and water intrusion. The larger the number, the higher the level of protection.

The soil pH sensor is best to choose the product with high protection grade IP68. The number 6 means completely preventing foreign objects and returning to the city. The number 8 means preventing water intrusion during the sinking. It is the highest to prevent continuous immersion in water with a depth of more than 1 meter. Protection level. Completely sealed, waterproof, anti-corrosion, and anti-interference, it can be buried in soil for long-term dynamic monitoring.

Pay attention to the probe of the soil pH sensor

The probe needs to be inserted into the soil to make direct contact with the soil, and it is best to use high-quality ones. For example, austenitic 316 stainless steel is used as the raw material, which can prevent rust, electrolysis, and corrosion of salt and alkali. It is also suitable for various soils.

Be easy to use

When choosing this type of product, it is best to choose a product with a low threshold and simple steps, which can be used for rapid measurement, without the use of reagents, and the number of tests.
