<p>The analyser comprises an ascending plate carrying the containers for determining the absolute viscosity at 50 and 100 degrees C and the viscosity loss. Two d.c. motors, agitators and closing resistors constitute a viscosity comparator and a double photometer. The test pipes, a light source and phototransistors permit carbon determn. based on dilution and controlled acidity, and a frame with a carrier shaft also make up the installation.</p> |
