NLA Diagnostics (NLAD) manufactures test equipment for the detection of micro cracking, disbonding, delamination, voids and thermal degradation in composite materials. The NLA DEFENDER® employs non-linear harmonics and impact resonance technologies to enable detection capabilities that provide an immediate "good/bad" indication while capturing the test data and storing up to one million files for subsequent in depth evaluation. In March of 2015, NLAD introduced the new NLAD Cheetah™ for specific testing properties requested by the aerospace industry. The NLAD Cheetah™ utilizes impact resonance for faster testing times, data storage up to ten million files and spatial recognition capabilities, in a smaller unit. Additionally, NLAD has entered the infrastructure evaluation market with the NLA RECON™ that employs similar technologies to evaluate the material condition of concrete structures.
