The relative humidity level deeper in the slab gives the truest measurement of the overall moisture condition.
Relative humidity testing equipment.
The pce thb 38 relative humidity meter is ideal for detecting and digitally displaying humidity temperature and barometric pressure.
The lower the humidity the faster the evaporation rate and the greater the cooling of the bulb.
Other tests are surface based and do not give reliable results.
Ats performs condensing humidity testing utilizing specialized humidity cabinets.
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.
For successful flooring projects it is crucial to measure moisture below the surface of the concrete slab.
Our environmental testing lab is iso 17025 a2la accredited to perform this method to astm d2247 and astm d4585.
Tools and accessories for concrete moisture testing.
The wet bulb will register a lower temperature than the dry bulb in air that has a relative humidity rh between 0 100.
It involves setting test chamber conditions to an internal temperature of 85 degrees celsius and a relative humidity index of 85 percent.
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.
For example the anhydrous calcium chloride test measures only the moisture vapor emission rate coming from the slab s surface.
Relative humidity test kits.
All products are test instruments and the relative humidity meter is sent out manufacturer calibrated.
Why relative humidity testing.
These methods help determine the coating performance by exposing test panels or actual parts to an atmosphere maintained at 100 relative humidity.
Temperature is measured by an rtd sensor and air humidity is measured by a highly repeatable capacitive sensor.
American moisture test manufactures world class professional grade concrete moisture test kits and concrete moisture realted equipment and supplies.
The 85 85 test uses a temperature and humidity testing threshold that applies to the vast majority of environmental evaluations.
The higher the humidity the slower the evaporation rate hence the bulb is cooled to a lesser degree.
