Historical data

One of the first hubodometers was designed by Engler which was later bought by Stemco and sold under the brand of Stemco Engler Hubodometers finally ending with the Stemco Hubodometer in the early 80's. The first hubodometer with no moving parts was made by Stemco and released in 2002 under the name DataTrac. This part was then made programmable in 2006. In 2005 the first solid state hubodometer was made into a backscatter RF device later being converted to an active RF mileage data collection device in 2007 and named the Active TracBat hubodometer. This newest version can be read by satellite asset tracking systems or gate reader systems as well as with handheld readers. It also still included the visual display that had been used on the datatrac device.
