The only difference between the models is that the TL3-A doesnt utilize the wireless function compared to the model TL3-R and TL3-W. The primary model tested, the TL3-R, is a higher precision variant compared to either the TL3-W or TL3-A. The TL3-R has a better tolerance, larger temperature range and slower temperature response, all of which are achieved through firmware while the PCB layout, schematic, and enclosure remain the same.
