[JXCT] 7 in 1 EC PH NPK Moisture Temperature Meter

The soil integrated sensor is suitable for measuring soil temperature, moisture, total soil salt (conductivity), soil pH and nitrogen, phosphorus and potassium. The soil comprehensive sensor creatively measures the seven parameters of conductivity, moisture, temperature, ph, and nitrogen, phosphorus and potassium, which greatly facilitates the customer's systematic assessment of soil conditions. .

Compared with the German original high-precision sensor and the actual soil drying weighing method calibration, the sensor has high accuracy, fast response and stable output: it is less affected by the salt content of the soil and is suitable for various soil qualities. Can be buried in the soil for a long time, resistant to long-term electrolysis, corrosion resistance, vacuum potting, and completely waterproof.

It is widely used in scientific experiments, water-saving irrigation, greenhouses, flowers and vegetables, grassland pastures, rapid soil testing, plant cultivation, sewage treatment, grain storage, and the measurement of various particulate water content and temperature.

Note: The details of all measurable parameters of this series of products, please refer to the actual product purchased.

When measuring frozen icy soil layers, the moisture value will be low and inaccurate, requiring user compensation.

The factory default product is suitable for measuring ordinary yellow soil, black soil and red soil. It is not suitable for absolute moisture measurement on saline-alkali soils, sandy soils, or other powdery objects with high salinity. It can still characterize the relative moisture difference. For this type of moisture measurement, you should contact the manufacturer for separate calibration.

The soil moisture calculated by this sensor is soil volumetric moisture content (also called soil volumetric moisture content), which is what people call "soil moisture" and "soil moisture" in a popular sense.

The calculation method of soil volumetric water content is the ratio of the volume of water in the soil to the total volume of the soil. 0% means completely dry soil without any moisture, and 100% means completely water without any soil.

This sensor can be connected and used alone. First, use 12V DC power supply. The device can be directly connected to a PLC with a 485 interface, and it can be connected to a single-chip microcomputer through a 485 interface chip. The single-chip microcomputer and PLC can be programmed through the specified modbus protocol to cooperate with the sensor. At the same time, use USB to 485 to connect to the computer, and use the sensor configuration tool provided by our company for configuration and testing.
