One pair of insulated electrodes (ø 4 mm) for targeted moisture measurement in concealed component layers where the electrode shaft needs to be insulated. An absence of insulation would falsify the measuring result.
The most frequent use is the determination of moisture distribution of multilayered wall or ceiling structures such as floating screeds, multilayered walls, wooden beam ceilings, warm roofs etc. The TS 12/300 electrodes have a diameter of 4 mm and a length of 300 mm.
