The CP40II Cone Penetrometer creates a new parallel between ease of use and superb accuracy. This compact instrument is the world’s best handheld tool for soil surveys involving compaction, trafficability and moisture distribution. Ultrasonic depth sensing, coupled with the optional GPS, makes both this unit and the data you collect extremely accurate.
Now with a maximum depth measurement of 750mm, with intervals of 10, 15, 20 and 25mm, it is possible to record up to 75 cone-index data points per penetration/insertion. The increased memory capacity of the CP40II Penetrometer means it can now store data from over 2000 individual insertion readings. Each insertion is capable of having an 18 character sitename, full GPS readings, and useful parameters such as maximum depth, interval as well as time and date of insertion. Additional features include the ability to store the type of GPS being used, either GPS or DGPS (Differential GPS), and the size of the cone being used.
