The CL-10DV series Asphalt Viscosity Meters are used to measure the viscosity of hot liquid asphalt. These viscometers are used in the roofing industry to measure the viscosity of asphalt filled with powdered limestone. Filled asphalt is primarily used to make roofing shingles.

Another use for the CL-10DV Asphalt Viscosity Meter is in asphalt adhesive. Once shingles are manufactured, the shingles are glued together with asphalt adhesive. By controlling the viscosity, a very high quality shingle can be manufactured that does not waste basic materials.

The Asphalt Viscosity Meter consists of a Dynatrol^® Viscosity probe, a Series 3000 Viscosity Converter and a VRO-1 signal conditioner. Dynatrol^® Viscosity probes are manufactured for use in very unforgiving environments, such as those found in roofing material plants. The Dynatrol^® Viscosity probes can withstand high temperatures, dust, dirt and a wide range of line voltages and at the same time send out very accurate viscosity information.
