With its outstanding features, TIME3231 is capble of performing various difficult roughness measurements. By working with different probes, TIME3231 can perfectly test different parts of the piston. Take the ring groove for example. The testing space is very narrow. TIME3231 can skip the run-up distance to cover as much evaluation length as possible. When it comes to the side surface of the ring groove, the pen-tip pickup (TIME S232) is small enough to go inside.
