Scissometers

The scissometer is used for in situ measurements of the shear strength of cohesive soils. Scissometer surveys are fast, economical, have good repeatability, and provide reliable results for planning further investigations.

We offer 4 scissometers according to your needs:

• Scissometer H-60 (test depth: 3 metres)
  The small, lightweight instrument can be stored in a carrying case. It allows the stability of foundations, excavations and ditches in clay to be determined quickly and easily. The special design of the extension rods gives the fittings a high resistance to buckling. Tests can be carried out to a depth of 1-2 metres in hard clay and up to 3 metres in soft clay. The scissometer can measure shear strengths of 0-60, 0-130 or 0-26 kPa depending on the (interchangeable) blades used.
• H-70 Scissometer (test depth: 10 meters)
  The scissometer is specifically designed for preliminary investigations in soft clays without pre-drilling. It allows for investigations up to 10 meters deep through simple hammering or driving the auger. It is a lightweight, portable instrument that requires only a single operator. It is the only instrument equipped with a friction-free coupling system that allows for 180° measurement, ensuring accurate recording of the actual value of lateral soil friction on the rods. The winch itself is made of high-quality stainless steel.
• H-10 Scissometer (test depth: 30 metres)
  The H-10 Scissometer is equipped with a reel that is fully protected and sinks under pressure. No rod-ground friction is possible thanks to its protective tubes. There is also no need to check the reel or clean it between shears (the clay adhering to the reel can considerably increase its surface coefficient). The H-10 Scissometer's protective shoe not only protects the reel but also automatically cleans it before each measurement. The shoe is particularly useful for testing stratified, sandy, stony and marine sedimentary clays. The H-10 Scissometer allows investigations to a depth of 30 metres.
• 
  CPT Electric Shear Meter (Test Depth: 25 meters) This electric shear meter, used in conjunction with a CPT static penetrometer, is the top-of-the-line model among shear meters. It is controlled by a PLC (Programmable Logic Controller) and features a high-precision torque sensor. The test procedure and data acquisition are fully computer-controlled. The measured data is displayed in real time and recorded simultaneously. This shear meter is compatible with standard CPT rods and tubes, which reduces costs for companies already equipped with CPT equipment.
