We recommend BNC technology with coaxial cables for the transmission of weak DC currents, low-frequency AC currents or in laboratory use. The coaxial construction of the cable provides protection against electrical interference and fields with the outer conductor. This reduces errors when measuring signals with low voltage.
You can find a specially developed cable for laboratory use here!
