Traffic Tally 51 Vehicle Traffic Counter and Accumulator

Traffic Tally 51 Vehicle Traffic Counter and Accumulator - Discontinued

The TT-51 consolidates the 14/21/41 units into one solid product option and is recommended as a replacement to the older unit form factors.

The TT-51 accumulator has solid-state electronics that are compatible with inductive loops buried in gravel or cut into roadway pavement. The counter has a very low power draw and will operate for one year on a set of eight “D” cell alkaline batteries.

The TT-51 is an industrial grade unit that operates in most environmental conditions.
