    NF Moisture-Density Gauge
    General In formation:
    With cumulative years of development,research,application and production of Surface Moisture-Density Gauge,Nanjing Hydraulic Research Instirute and our company has developed the NF Moisture Density Gauge based on the wide adoption of advantages of similar instrumcnts from homc and abroad.
     The NF Moisturc-Dcnsity Gaugc makes rapid moisture and dcnsity mcasurcmcnt of soil,stone,concrete or asphalt concrete simultaneously by emitting gamma ray directly into the tesled materials and deleeting the transmission or seattering gamma ray intensity.The soil moisture probe with the most advanced technology in the world is highly precise,reliable and aurable.The NF Moisture-Density Gauge with nondestructive,fast delection and control can be widely used in compaction test in the site of roadbed,railwaybed,airport runway,embankment,dam and the base of high-rise building.It is an essential and ideal instrument for the deteetion adn control of compaction quality for Civil Engineering Laboratory,Project Supervision,Quality Supervision Departments and Construction Units.
