ATRT-1150 Automated Traffic Recorder Tester
The ATRT-1150 is an automated tester capable of testing Road Tube Axle sensors on counters and classifiers used in today's traffic industry.  The counter/classifier under test must be able to count multiple axle vehicles that pass over Road Tube sensor arrays and allow the user to determine the counter/classifier count for the test period.  The user also has the ability to control the level of the output signal being sent to the counter/classifier. When a test is completed, the data can be compared to the classifier's report for possible variances that may have occurred.
