Our flagship product, the PQI, is what put TransTech Systems on the map. The PQI is our NON-NUCLEAR asphalt density gauge. Precise density measurement is nearly instant (3 seconds). The PQI is more accurate than the nuclear gauge but without the hassle of regulatory training and certification. Easy for your crew to use! The PQI 380 complies with ASTM D7113 and AASHTO T343.
