A triad would only provide you with three wires/conductors/cores, and a properly-applied 4-wire RTD requires 4 (four) wires/conductors/cores. You could use two (2) two-wire (conductors; cores) twisted, shielded pair cables for a total of four wires/conductors/cores--which is what should be used for a 4-wire RTD.

Treatment for dandruff and itching scalp Regular washing of the scalp with medicated soaps may be all that is required to relieve itching scalp. The most common anti-dandruff shampoos contain one or more of: 1  zinc pyrithione or zinc omadine. 2  selenium sulphide. 3  piroctone olamine â this is the most recent addition to the medicated shampoos. 4  antifungal agents. 5  tar â shampoos containing tar have been used for years, usually for more severe scalp conditions.
