Soil four parameter meter introduction:
HLY-B04 adopts the principle of standing wave type measurement, and is used for rapid measurement and recording of soil moisture, temperature,salinity and pH. It is widely used in agriculture, forestry, soil moisture monitoring system, standard farmland project, intelligent irrigation control project, soil moisture satellite remote sensing monitoring system and seedling monitoring system, soil moisture real-time monitoring system, geological exploration, plant cultivation and other fields.
 
Soil four parameter meter​ Features:
1) The host is small in size, simple in software operation and reliable in performance.
2) The recording interval can be set from 1 minute to 99 hours as required.
3)The whole process is tracked and recorded for a long time. It integrates data acquisition and recording, and has the function of automatic storage and protection of power failure data.
4) The whole machine has low power consumption, battery and utility.
5) The software has powerful functions and convenient data viewing. The data in the recorder can be exported to the computer at any time, and can be converted into EXCEL form files, and data curves can be generated for further data processing by other analysis software, which is convenient for research and inspection.
