Push cone (soil hardness tester)

DIK-5553

0-40mm (0-49MPa)

● The push cone can easily measure the resistance value by simply pushing the cone perpendicular to the cross section of the soil that has been cut flat. 
● Compared to conventional hardness testers, this instrument has no slits, so there is no need to worry about soil getting inside. In addition, the resistance value is a direct reading type that is easy to see. 
● The resistance value is a direct reading type that is easy to see. 
● Small weighing and convenient to carry. 
● Measurement range: 0-40mm (0-49MPa)
● Cone angle: 25 ° 20'
● Spring strength: 78.4N / 40mm

Digital soil hardness tester (digital push cone)

DIK-5557

0-40mm, 0kPa-∞ (1948574kPa at Max 39.5mm)

It is a digital soil hardness tester that can display the scale (mm) and supporting strength (kPa) at the same time.

Crust hardness tester

DIK-5561

A crust hardness tester that can easily measure soil hardness suitable for germination.
● When cultivating soybeans, the surface of the soil may be too hard and the soil film may resist germination, which may hinder the growth of the buds. To avoid this, it is necessary to keep the soil hardness suitable for germination at all times. The crust hardness tester can easily measure the soil hardness suitable for germination. ● Spring strength (1 each made of SUS): 9.8N / 40mm (white), 19.6N / 40mm (yellow), 39.2N / 40mm (red)
● Body dimensions: φ40 × 205mm
● Cone angle: 11 ° 25'
