Patent attributes
A probe assembly for measuring a synthetic turf infill profile having a probe, a turf surface contact assembly and a sensor. The probe is configured to extend down through the turf infill profile until a tip of the probe contacts a lower boundary of the turf infill profile. The surface contact assembly is vertically movable relative to the probe while the probe is being moved downwardly into the turf infill profile, wherein the surface contact assembly has a contact area with the turf surface that is large enough to retain the surface contact assembly resting atop an upper boundary of the turf infill profile when the lowermost tip of the at least one probe has contacted the lower boundary of the turf infill profile. The sensor reads the distance between the upper and lower boundaries of the turf infill profile at a sampled location in the turf surface.
