Rather than relying on traditional measurement by hand, our laser measurement system makes this process both instantaneous and accurate. The SmartDCP Method allows the measurements to be taken by one person, and data is transferred wirelessly to the DCP app to log data in real time. Contact Humboldt Mfg. Co. for more information. https://www.humboldtmfg.com/smart-dcp-for-dual-mass-penetrometers.html
