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
