One of the most regular causes of a coatings failure is moisture especially when applying to wood or building materials. Moisture meters are integral to the process of determining material readiness and suitability for coating application.
Many substrates in today’s industry such as wood, concrete, fibreboard, plasterboard, gypsum and brick that are coated are porous and can absorb moisture. It is therefore necessary to measure the moisture content within the substrate to reduce the possibility of subsequent coating failure. Powder coating substrates such as wood or MDF have a high moisture content and will generate steam during the curing process damaging the new coating applied. Other coating substrates including concrete, fibreboard, plasterboard, gypsum and brick may also have a high moisture content and again may damage any new coatings applied.
Dyne Testing offer a range of moisture meters and humidity meters to test these materials prior to applying coatings. The moisture meters vary in price from the economy range to the more deluxe which offer more features.
|Moisture Meter for Building Materials is an electronic moisture indicator based on a non-destructive dielectric constant measuring.||Moisture Meter for Building Materials Deluxe This version has more features. For a non-destructive measurement of moisture in building materials.|
|Moisture Meter for Wood Materials for wood materials and plaster is based on the resistance measuring method.||Moisture Meter for Wood Materials Deluxe This version has more features with 3-line LCD display. For diverse wood species, soft building materials and insulating materials.|
|Moisture Meter for Wood Fuels with average calibration including both soft and hardwood with a large three-digit LCD.
