Due to prolonged measurement work and repeated use of the machine for more than 2 years, cables will rub repeatedly on the ground. At this time, you have to reconsider adding ADMT multi-channel measurement cables. Multi channel equipment is divided into 16 channel and 32 channel. You can choose 16 channel to adapt 40M cables per roll, and 32 channel to 80M cables per roll, with each roll requiring 40M. 32 channel requires 2 rolls of 40M cables, and different customers choose different spacing. The standard spacing is 2.5m, but you can also consider using 5m spacing. The cost of using larger spacing will also increase accordingly
