Description

With digital display and microprocessor to control a vacuum pump 95-2475 to perform the following tests:

  • Binder recovery using a rotary evaporator EN 12697/3
  • Asphalt density test EN 12697/5, ASTM D 2041, AASHTO T 209
  • Determination of water sensitivity EN 12697/12

The controller is equipped with 2 modes to provide a depression with 3 pre selectable vacuum steps from 1000 to 20 mbar. Each step has an observation- and cycle time pre selectable from 0 – 99,99 h/min/s. Mode 1 is used for tests acc. EN 12697/5 and EN 12697/12 (standard vacuum steps 700-200-30 mbar). Once the preselected step is reached the vacuum pump is automatically stopped by the controller. When the preselected observation-/cycle time is expired the controller starts the vacuum pump again to continue to the next vacuum step. Mode 2 is used for tests acc. EN 12697/3. With this mode, each vacuum step is automatically controlled to remain constant. The vacuum pump 95-2475, the containers for density resp. water sensibility test 20-1435… and the rotary evaporators 20-1300… are not included and have to be ordered besides.
