The new TriOS telescopic rod provides a solid and reliable mounting method for the TriOS dissolved oxygen sensor. The sensor is permanently mounted in the head section of the telescopic rod and can be immersed in the medium by extending the telescopic tubes to a distance of 6.8m. The rod can be held by hand or attached to a railing or similar with the supplied double clamp. Due to the material mix of carbon and fiberglass, the rod is grippy and light at the same time.
