Model 3241-D Asphalt Content Gauge

    Model 3241-D Asphalt Content Gauge

    $0.75

    Troxler's Model 3241-D Asphalt Content Gauge enables you to quickly, accurately, and safely test your bituminous mixes for asphalt content using nuclear methods. Used by transportation agencies all around the world, the Model 3241-D provides accurate asphalt content results in as little as five minutes.

    No Toxic Chemicals or High Temperature Burns

    The Microlab provides the asphalt content measurement without the hazard and expense of the toxic chemicals employed in the solvent extraction method. This method is also beneficial when analyzing the material that may be lost in a high temperature burn oven. 

    Simplifies Reporting and Reduces Calibration Time

    The Microlab downloads test data directly to a printer or computer, simplifying result reporting. Calibration transfer from a centrally located 3241 gauge greatly reduces calibration time for field sites.

    The 3241-D gauge meets or exceeds ASTM Standard Test Method D-4125. Troxler's asphalt content measurement equipment is used as the standard test method by more than 25 states and federal transportation agencies. Hundreds of highway construction contractors and testing authorities use the 3241-D for quality control and acceptance testing.
