Moisture meters (materials)

Portable moisture meters  - SA7825PS

This instrument is an N.D.T. for moisture detection inside a wide range of materials. There are many types of measurers on the market, they can be divided in contact instruments(they measure the dieletric characteristic of woods) and in piling (PIN – they measure the resistance between two electrodes) Humidity is the water percentage inside a material and depending on its level it can compromise production process,physical characteristics and have important parameters on manteinance and quality control. Contact Instruments - Search Type – 

They allow depth measures thanks to generated electric field. Measured value is an humidity average value calculated with decreasing sensibility on depth increasing. Instruments with in piling probe – PIN type – :The measure electric resistance between two electrodes .The value is taken in the space between them , at the piling depth. Measured value is the maximum humidity detected between electrodes. Piling mode is more indicated when… Material has humidity lower than 8-10%,not damage the material ,wood surface has been soaked by frost, quick multiple measures. Contact mode is more indicated when… Material has humidity above 20-30%,thickness lower than 2cm and it’s not possible to stack more layers without air gaps. Probably humidity isn’t uniformly distributed , measure velocity and material damage are secondary to accuracy requested. Accuracy Due to non-homogeneous nature of woods, instruments performance can’t be ensured on different samples different from those tested, even if they are from the same species. Characteristics Wide measure range and high precision; Large display for correct value reading; Versatility and reliability for humidity diagnosis in buildings and construction materials.
