Description
The NCAT field permeameter is for those who don’t wish to buy the complete kit or who need to replace an existing one. This field permeameter is the same permeameter used in the HM-9113 kit. The HM-9113.1 permeameter is supplied in two sections and constructed of rugged plastic. In use, sealing material is placed on the base plate and the unit seated against the pavement using gentle foot pressure and included base weights. After filling with water, outflow is observed using the clearly marked graduations. The smallest, uppermost tier allows rapid determinations in low-porosity pavements. The larger diameter tiers are used to accurately read flow on more porous pavements.
