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
