This is a complete set for obtaining penetration values in most soils to a depth of 3 meters. The auger provided with this set is to make measurements at greater depth than 1 meter without probe hole soil adhesion to the probe rods at deeper depths. Useful in determining foundation acceptability for buildings, compaction characteristics of soils due to road use or settling, problems associated with plant root migration or sprouting or in determining compacting of various layers at depth within a soil profile. It’s an easy to operate system with little maintenance needs that transports conveniently to and from the field in it’s protective aluminum case. With a measuring range of 0-10000kN/sqm and 1 kPa scaled meter and max holdoff indicator it’s everything you need for deeper penetration measurements.
