    摘要： An electronic measuring technique for use in determining the end point of a process, such as an air blowing process employed in the manufacture of asphalt, by means of an electronic bridge circuit, a device for monitoring continuously certain electrical properties of the actual product, and a reference standard which simulates the preselected desired electrical properties of the product, such as oxidized asphalt, being manufactured. As the process progresses the difference between the sensed electrical properties of the actual product and those simulated by the reference standard decreases and becomes zero or nearly zero at the end point. When the difference is zero, provision is made for the process to be stopped automatically or manually, whereupon the product is transferred into its respective storage area.
