Cobra Xpert-Link

Professional datalogging in one system

The universal interface for demanding scientists.

The Cobra4 Xpert-Link is the professional device for datalogging applications with a computer (Windows, MacOS and Linux). All important measurable quantities in physical, chemical and biological sciences can be recorded, thereby curricular requirements can be completely covered.

Your benefits:

  • Measurement instrument for all types of measurements
  • Direct measurement of voltage and current, no additional accessories required
  • Datasharing in demo experiments: transfer of measurement data from teacher computer to student tablets
  • Students can use their own computers in the teaching lab
  • Many additional quantities can be measured with Cobra4 Sensor-Units from the fields of physics, chemistry, biology and applied sciences
  • Can be used as a digital oscilloscope
  • Automatic sensor recognition
  • The 4 voltage and current channels measure independently
  • High resolution at large measurement range
  • Long-term measurements possible: data amount only limited by size of computer RAM
  • Detailed at a glance
