HMP SONpro-M
suitable for all common mechanical penetrometer

HMP SONpro-P
suitable for all common pneumatic penetrometer

The measuring instrument HMP SON-M records the stroke rate using radar. Simultaneously to that an ultrasonic sensor determines the penetration depth. The number of Strokes per 10 cm of penetration depth is automatically recorded and stored.

The measuring instrument HMP SON-P records the stroke rate using a pressure sensor. By pressing the foot switch every 10 cm of penetration depth, the number of strokes is recorded and stored for that penetration depth.
