Function and Applications
The Cobra4 Xpert-Link is the perfect measurement device for all demo experiments and for lab courses.
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
