Cobra4 Xpert-Link

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
