Watertight Two Tube Time Interval Counter
The Traffic Tally 8 will provide a grand total and up to 10,240 separate interval volume counts into memory and has a battery life of 5 plus years in the field. The TT-8 has two road tube inputs for multiple lane counts.
The magnetic control switch prompts the display to show the total and interval data while a second magnetic switch located on the side will select one or two channels, lane subtract or normal, interval length, and will zero interval data.
