Rapid testing methods refer to on-site operational methods that require no complex sample pretreatment and can yield results within minutes. Today we will examine rapid testing methods for soil moisture, temperature, salinity, and pH.
Let's start with soil moisture and temperature. Portable soil moisture rapid testers can be used, utilizing the characteristic that soil's dielectric constant is highly correlated with moisture content. The instrument probe emits electromagnetic waves and measures changes in propagation frequency or time to calculate soil volumetric water content. This method is fast, non-destructive, does not damage soil structure, allows multiple repeated measurements, and many models can simultaneously measure temperature.
Next is soil salinity, which is usually indirectly reflected by measuring the electrical conductivity of soil extracts using a soil EC meter. The principle is that salt ions in the soil can conduct electricity; the higher the salt content, the greater the conductivity value. Soil salt content is inferred by measuring the electrical conductivity of soil-water mixtures.
Finally, soil pH is measured using a soil pH meter, which utilizes the response of a pH glass electrode to hydrogen ion concentration in solution to generate a potential difference, thereby determining the pH value. This method is faster than laboratory testing and more accurate than paper strip measurements.
Currently, there is an instrument on the market called a multi-parameter soil rapid tester. One main unit can connect multiple sensors for moisture, temperature, EC, pH, etc., and can even be directly inserted into the soil to measure multiple parameters simultaneously, greatly improving efficiency.
The FT-WSYP1 Soil Temperature, Moisture, pH and Salinity Meter is an integrated design portable device that can quickly measure key soil parameters to help you comprehensively understand soil conditions.
The instrument adopts an integrated structural design, making it very convenient for field carrying. The main unit can collect multi-parameter data in real-time and is equipped with a large-screen color LCD display for intuitive reading.
The instrument supports manual storage and automatic interval sampling, with a built-in large-capacity memory (capable of storing 10 million data points). Data can be exported to a computer via USB interface for further analysis. The sensor has automatic identification functionality and supports multi-channel expansion, allowing users to flexibly combine sensors according to needs to achieve multi-point synchronous detection.
In summary, the FT-WSYP1 rapid tester is suitable for users who need to quickly obtain multiple soil parameters simultaneously on-site. If you need more long-term unattended monitoring or wish to wirelessly transmit data to the cloud for management and analysis, then you may consider a dedicated soil moisture monitoring system for long-term buried point monitoring.
