Product name Platinum matrix matrix conductivity test platform/HZC-601

Product details

      Product Description

       Platinum substrate sub conductivity test platform/HZC-601 consists of 2 splints and 2 platinum-plated platinum black test electrodes. The size of the splint is 60×50×12mm, the effective area of the film channel is 20×20mm, and the material is PTFE. The test electrode is platinum-plated black electrode, self-made electrode, the platinum-black area is 18×8mm, the effect meets the requirements of textbooks; The electrode was connected by 4 platinum wires, and the purity of platinum wire and platinum plate was 99.99%.

      The platinum-black electrode is a fluffy and porous layer of platinum. The porous platinum black increases the surface area of the electrode, reduces the current density and reduces the influence of the polarization effect of the electrode. Platinum or poorly plated platinum black electrode can not be used, which will seriously interfere with the accuracy of the experimental results.

      Test principle:
     Sigma = a/(R·b·d)
     σ -- The proton conductivity of the sample, S/cm
     A -- Platinum black electrode spacing, cm
     R -- Sample electrochemical impedance value,Ω
     B -- The effective length of the film perpendicular to the platinum black electrode, cm
     D -- Thickness of sample, cm
