The non-Arc version of the Visiferm has the ability to simulate a traditional electro chemical sensor (ECS) output. This small nA output signal requires more insulated double coaxial cables. For attachment to common bioreactors a variety of standard connectors cables are provided. They come with wall power supplies to power the internal µ-transmitter. The VisiPro and VisiTrace use a low cost M12-4 cable and can be powered by a 2 wire 4-20 mA loop.
