Replace your old black and white monitor from your TST 507 system with the TST 507 color monitor. The 507 color monitor displays both PSI and temperature of each tire all on the same screen. This monitor can handle up to 4 different trailers. The screen is 3.5 inches by 1.75 inches, so you can see the brilliant color screen very easily. This monitor works with the TST 507 sensors including the cap, flow thru, hybrid, and internal sensors. The monitor can easily drop the towed vehicle wheels from the screen, or drop the RV wheels from the screen so that you can transfer the monitor to your towed car or truck.
