  • KETT
  • $10.00

The HX-300 displays the moisture (%) by the simple insertion of a needle-shapedsensor into the surface matting, or tatami stuffing ("tatamidoko"). It is known that the moisture content of the stuffing and atmospheric temperature are big factors in the outbreak of tatami matt lice infestations. Further, high moisture content in the stuffing can also be the cause of fungi and decay. Recently, there has been an increasing move from rice straw tatami stuffing to different types of building materials. This moisture tester can measure the moisture content of tatami surfacing, rice straw stuffing and tatami board (wooden board flooring material), control of the moisture content of which is prescribed by both the Japan Industrial Standard in particular, as well as the Japan Agricultural Standard.
