Video
Product Features
1. Corrosion-resistant Solid AgCl electrodes
Compared with the traditional alloy electrode, the AgCl reference electrode used in this sensor, corrosion resistance.
2. Easy measurement
Soil PH testing is no longer limited to laboratories and professionals, and can be measured by inserting into the soil.
3. High precise with
Using high precise AgCl probes with three points calibration which can keep in high precise, error can be within 0.02.
4. With temperature compensation and also can measure soil temperature value
The PH sensor has temperature compensation inside, which can realize the pH value stabilization within a certain temperature range.
5. Low measurement cost
Compared with traditional laboratory measurement, this product has low cost, fewer steps, no reagents required, and unlimited testing times.
6. More application scenarios
Not only can it be used in the soil, but it can also be used in hydroponics, aquaculture, etc.
7. High precision, fast response, good interchangeability, probe plug-in design to ensure accurate measurement and reliable performance.
Product Applications
The sensor is suitable for soil monitoring, scientific experiments, water-saving irrigation, greenhouses, flowers and vegetables, grassland pastures, soil rapid testing, plant cultivation, sewage treatment, precision agriculture and other occasions.

Product Usage
Soil Surface measure method
1. Select a representative soil environment to clean up surface debris and vegetation.
2. Insert the sensor vertically and completely into the soil.
3. If there is a hard object, the measurement location should be replaced and re-measured.
4. For accurate data, it is recommended to measure multiple times and take the average.
Buried measure method
1. Make a soil profile in the vertical direction, slightly deeper than the installation depth of the bottommost sensor, between 20cm and 50cm in diameter.
2. Insert the sensor horizontally into the soil profile.
3. After the installation is completed, the excavated soil is backfilled in order, layered and compacted, and horizontal installation is guaranteed.
4. If you have the conditions, you can put the removed soil in a bag and number it to keep the soil moisture unchanged, and backfill it in reverse order.
Six-tier installation
Three-tier installation
Measure Notes
1. The sensor needs to be used in 20% -25% soil humidity environment.
2. All probe must be inserted into the soil during measurement.
3. Avoid excessive temperature caused by direct sunlight on the sensor. Pay attention to lightning protection in the field.
4. Do not pull the sensor lead wire with force, do not hit or violently hit the sensor.
5. The protection grade of the sensor is IP68, which can soak the entire sensor in water.
6. Due to the presence of radio frequency electromagnetic radiation in the air, it should not be energized in the air for a long time.
