Combining high accuracy, functionality and portability in a measurement instrument can be a difficult task.
The D2001, Aethra's hand-held tester, has achieved this goal: a perfect measurement instrument delivering complete and immediate analysis of ISDN lines in a very small footprint.
In addition, the zoom function makes information control easier, ensuring quick data verification.
Because of its small size and anti-glare display for excellent visibility in poor light conditions, the D2001 can be used virtually anywhere.
