4G version of soil conductivity meter

Introduction:

The soil conductivity meter is a portable conventional measuring and analyzing instrument with an integrated structural design. It can display soil conductivity and salinity values at the same time. It consists of a portable host, sensor, software, etc. and is easy to operate.

Scope of application:

The instrument is widely used in dryland water-saving irrigation, precision agriculture, forestry, geological exploration, plant cultivation, greenhouse planting, water conservancy, environmental protection, scientific experiments and other fields.

Outstanding performance:

Adopting integrated structural design, built-in GPS module, GPRS module, external SD card, it can accurately measure the geographical information of the measured location. In addition to displaying the measured environmental parameters and storing data, the interface can also display the latitude and longitude of the measuring point. The built-in GPRS can upload the environmental factor measurement data of the measured point with one click. At the same time, the data can also be directly exported to the computer through the external SD card.

The machine is small and beautiful, simple and convenient to operate, reliable in performance, and extremely convenient to carry in the field. After the host is connected to the sensor, the records can be stored manually or the sampling interval can be set arbitrarily through the host to automatically store the recorded data.

The large-screen Chinese LCD display can track and record the values, groups, and low voltage warnings of each environmental factor being measured. The host has a built-in large-capacity memory that can store 300,000 data and has a power-off data automatic storage protection function.

After each sensor is inserted into the host, the host has an automatic recognition function. The sensor has good consistency and can be combined as needed. Sensor interfaces with different parameters can be converted to each other without affecting the measurement accuracy.

The instrument has a multi-channel automatic detection expansion function, which can realize synchronous detection of multiple sensors connected at the same time.

The host computer software is powerful and can export the recorded data to the computer through the USB interface at any time, and can be stored as an EXCE table file to generate data curves for further data processing by other analysis software. It has the function of setting the coloring of the over-limit area and the color change warning of over-limit data, which can be used as a basis for environmental evaluation.
