U-DC Single channel w/multichannel receiver 17Bit, 60V, 10Hz

The U-DC system is a unique product that makes measuring DC voltages easier. With an integrated display and output, additional measurement devices are not required. Up to 8 channels can be integrated into the 19" rack-mount receiver (outside the chamber), and each channel is attached to its own transmitter block. This system is ideal for accurately measuring voltages, and a fast response is unnecessary. The response time is 10Hz. Alternatively, the Ux/14 analog measurement device can be used.
