Overview
The instrument is a special instrument for testing soil Hardness. Compacting soil can prevent water infiltration, reduce the utilization rate of chemical fertilizers, affect plant root growth, and even lead to crop yield reduction. Therefore, soil compactness is particularly important for guiding agricultural production, which can guide arable land methods and highway construction well.
Features
1. High Accuracy, High resolution
2. Numbers are displayed, ignoring the difference
3. Four measurement units of N (newton), kg (kilogram), lb (pound), g (gram) are available and converted to each other
4. Peak hold function, keep peak display until manually cleared
5. Can be powered by alkaline battery; can also be connected to 5V DC power supply
Principle
The instrument detects soil compactness by measuring soil Hardness. Measurement range 0-100kg (0N-1000N), test depth 0-30cm, can test various backfill soil, clay, sand and mixed soil after rolling.
Applications
Highways, railways, reservoirs, dikes, dams, and civic buildings
Steps
1. Select the appropriate Measurement unit (N, kg, lb, g)
2. Insert the instrument Probe into the soil to the desired depth
3. Read and maintain peak display
4. Manual zero after the next measurement
5. Power supply with 2 AA batteries or 5V DC power supply
