I am interested in a TST system. They have one called the 507 and another one is 510. What is the difference between the two an which one would be better?
I wrote an email to TST, but they seem not to monitor their email system very well,. because I have not gotten an answer for more than a week now.
The 507 has the flow-through monitors and the 510 has the standard monitor that you remove to add air.
IMO the flow-through monitors are pretty much a pain if you have to add air because they have such a restricted flow. It can take quite a while to add as little as 5 psi to a tire. I have the 507 and when I have to add air, I remove the sensors, so they serve no real purpose for me. If I had to choose, I would go with the 510 system.
The 507 system has flow-thru, non flow-thru, and internal. The batteries are owner replaceable.
The 510 system does not have owner replaceable batteries (5 year life) and is more designed for big rigs.
