Relative Humidity Testing Equipment

For example the anhydrous calcium chloride test measures only the moisture vapor emission rate coming from the slab s surface.

Relative humidity testing equipment. Wagner rapid rh testing kit fast accurate relative humidity test for concrete floors gives flooring and building professionals the concrete moisture data they need to meet the astm f2170 standard. Astm f2170 acknowledging the benefits of rh testing in preventing flooring failures as documented in the scandinavian research astm international issued a new industry standard in september 2002 astm f2170. Relative humidity test kits. The 85 85 test uses a temperature and humidity testing threshold that applies to the vast majority of environmental evaluations.

American moisture test manufactures world class professional grade concrete moisture test kits and concrete moisture realted equipment and supplies. The relative humidity level deeper in the slab gives the truest measurement of the overall moisture condition. Our environmental testing lab is iso 17025 a2la accredited to perform this method to astm d2247 and astm d4585. Relative humidity and moisture test kits positector cmm is the positector cmm is probe is a self contained relative humidity meter which when working with the free mobile app guides users through the astm f2170 testing and documentation criteria.

All products are test instruments and the relative humidity meter is sent out manufacturer calibrated. The pce thb 38 relative humidity meter is ideal for detecting and digitally displaying humidity temperature and barometric pressure. It involves setting test chamber conditions to an internal temperature of 85 degrees celsius and a relative humidity index of 85 percent. Tools and accessories for concrete moisture testing.

Temperature and humidity measuring devices track temperature changes humidity levels and other climatic conditions in commercial and industrial environments. Other tests are surface based and do not give reliable results. Why relative humidity testing. The wet bulb will register a lower temperature than the dry bulb in air that has a relative humidity rh between 0 100.

For successful flooring projects it is crucial to measure moisture below the surface of the concrete slab. The higher the humidity the slower the evaporation rate hence the bulb is cooled to a lesser degree. Temperature is measured by an rtd sensor and air humidity is measured by a highly repeatable capacitive sensor. These methods help determine the coating performance by exposing test panels or actual parts to an atmosphere maintained at 100 relative humidity.
