License Exempt, Troxler Accurate

From the inventor of the nuclear density gauge comes the ONLY combination nuclear gauge that is License Exempt!

License Exempt
  • Less hassle and saves money.
  • Eliminates: RML, Reciprocity, TLD Badges, Storage Requirements, Transportation Requirements, Double Locks, Leak Tests, Record Keeping, Emergency Procedures, Expensive Shipping, Radiation Safety Training, and Military Base Restrictions
  • Going with license Exempt equipment also eliminates the risk of a surprise inspection by the state regulatory agency or NRC.
 
Combination Design
  • Direct Transmission, compliant with ASTM D8167. 
  • Standard Test Method for In-Place Bulk Density of Soil and Soil-Aggregate by a Low-Activity    Nuclear Method (Shallow Depth)
  • Backscatter, compliant with ASTM D2950 (and D8167).
  • Standard Test Method for Density of Bituminous Concrete in Place by Nuclear Methods
 
Accurate
  • Lab tested to hold similar accuracy as licensed nuclear gauges
  • Extremely accurate and more reliable than non-nuclear devices
  • Saves time due to not needing an offset/correlation
 
License Exempt nuclear density gauge, only available through Troxler.
