Soil salinity analyzer

Introduction:

The soil salinity analyzer is a portable conventional measurement and analysis instrument that adopts an integrated structural design and can measure soil salinity. It consists of a portable host, sensors, software, etc., and is easy to operate.

Applicable scope:

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

Outstanding performance:

Adopting an integrated structural design, with built-in GPS module, GPRS module, and external SD card, it can accurately measure the geographic information of the measured location. The interface not only displays the measured environmental parameters and stored data, but also displays the longitude and latitude of the measurement point. Upload environmental factor measurement data of the measured point with one click through the built-in GPRS. At the same time, data can also be directly exported to a computer through an external SD card.

This machine is compact, aesthetically pleasing, easy to operate, reliable in performance, and extremely convenient to carry in the wild. After connecting the sensor to the host, records can be manually stored or automatically stored by setting sampling intervals on the host.

The large screen Chinese LCD display tracks and records the values, number of groups, and low voltage alarms of various tested environmental factors throughout the process. The host is equipped with a large capacity memory that can store 300000 pieces of data and has automatic storage protection function for power outage data.

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

The instrument has a multi-channel automatic detection extension function, which can achieve synchronous detection of multiple sensors connected simultaneously.

The upper computer software has powerful functions and can export the recorded data to the computer at any time through a USB interface, and can be stored as an Excel spreadsheet file to generate data curves for further data processing by other analysis software. It has the function of setting color for exceeding limit areas and providing color warning for exceeding limit data, which can serve as a basis for environmental evaluation.
