Model: 4540 Hãng sản xuất: Troxler – Mỹ Xuất xứ: Mỹ 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 Documents, 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 – Backscatter and Direct Transmittion Asphalt using backscatter, compliant with ASTM D2950 and AASTHO T 355. ASTM D2950: Standard Test Method for Density of Bituminous Concrete in Place by Nuclear Methods AASHTO T 355: In-Place Density of Asphalt Mixtures by Nuclear Methods Soil using direct transmission and backscatter, compliant with ASTM D8167. ASTM D8167: Standard Test Method for In-Place Bulk Density of Soil and Soil-Aggregate by a Low-Activity Nuclear Method (Shallow Depth) 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.
