Options

The Model 3241-D provides these features and benefits: Asphalt content measurement without the hazard and expense of the toxic chemicals employed in the solvent extraction method. Rapid measurement allows mix inputs to be altered so the project stays within specifications. Calibration transfer from a centrally located gauge greatly reduces calibration time for field sites. The Universal Sample System option provides the added convenience of measuring either the commonly used 4" or 6" laboratory compacted sample. Send data directly to a printer or computer, making results easier to report. A twelve-month warranty and fifty years of Troxler experience give you the confidence you deserve.
