Supply of SC-900 Soil compaction meter

First, use: 

 Field portable, used to measure soil compaction equipment, which is the pressure of the instrument. PSI or kPa values can be displayed to reflect the degree of soil compaction, can be connected GPS receiver. Soil compaction prevents water infiltration and reduce fertilizer use efficiency, affect plant root growth, or even make crop production by 30%. This instrument can be a good guide cultivation, fertilization, cultivation of plants is important. 

 Second, the principle: 

 When the pressure on the system, the probe tip and the soil contact, and feel the pressure, the pressure signal acquisition system, and through the built-in calibration curves, the pressure into the soil compaction, which is the pressure value. The collection also built into the system the data can be stored through the RS232 standard interface, the data can be downloaded to your computer. 

 Three components: 

 Compaction device host 
 Data Acquisition Software 
 GPS / DGPS cable (optional)

 772 can store data (access GPS data can be stored in 579) 
 RS232 interface, the standard data output 
 ASAE (American Society of Agricultural Engineers) design standards. 
 Can be accessed by GPS receivers, GPS mapping with the degree distribution of soil compaction. 
 Query and display the measurement results 2.5cm increments. 
 Figures show that PSI / IN or Kpa / CM. 
 Insert sound the alarm too quickly.
