CPT Cone


Standard sensors include a tip, sleeve, pore water pressure, seismic geophones (SCPT), inclinometers (x and y), and relative temperature.

Vertek digital cones provide higher load capacity and better accuracy than industry standards by decoupling the tip and sleeve load cells and sensing each independently.

Noise problems associated with cable length and low voltage signals of analog systems are eliminated because analog-to-digital conversion is performed down hole.

An overload capacity of 150% ensures you can safely push the cone to calibrated capacity without compromising cone integrity.

Our rigs are capable of traversing rough terrain and squeezing into surprisingly small spaces, so if your site is in an unusually tight or hard-to-reach spot...

Middle Earth Geo Testing has two CPT Rigs. CPT Rig 1 is based out of our Northern California Office, and Rig 2 is based out of our Southern California Office. Both Rigs are all-wheel drive, and both weigh 50,000 lbs.

Rig 1 is different than any other CPT rig in California; Rig 1 has I-Beams under that box of the rig, and the purpose of the I-Beams is to increase the weight of the rig to 80,000lbs by adding trench plates to the I-Beams.
