Product introduction:
HLY-EXSF03 can be connected with 1-6 channels of soil temperature sensor and 1-6 channels of soil moisture sensor at the same time, which is used to measure and store soil temperature and soil moisture parameters of soil surface and different depths. It has high measurement accuracy, large storage capacity and small size. The recorder has the advantages of simple operation and reliable performance. It can work independently without the computer, track and record the whole process, and has the function of automatic storage and protection of power-off data. The data storage is stable and not easy to lose. It is widely used in the measurement and research of agriculture, forestry, geology, farmland, water conservancy, forest, lawn, highway, railway maintenance, etc.

Features:

1. This machine is small in size, simple in software operation and reliable in performance. The recording interval can be set arbitrarily from 1 minute to 24 hours according to the requirements.           

2. The system can track and record the temperature and humidity data in the tested environment for a long time, and has the function of automatic storage and protection of power-off data.           

3. The power consumption of the whole machine is small, and the built-in battery power supply can reach more than half a year.           

4. The software has powerful function and convenient data viewing. The data in the recorder can be exported to the computer at any time and stored as excel table file to generate data curve for further data processing by other analysis software.           

5. A single recorder can access up to 6 temperature probes and 6 humidity probes to measure the distribution of temperature and humidity in soil.           

6. The recorder can work independently without the computer. When the current environment data needs to be viewed, the data in the recorder can be read by the computer through the communication interface.           

7. A recorder can simultaneously measure the temperature and soil moisture of multiple points.
