• Can be used with one hand thanks to the multi-choice directional button.

• Internal memory of 10,000 measurements in several batches.

• Statistics, date / time / location of each series of measurements and automatic calculation of the average roughness.

• Speed: 50 mm / s (indication on the sensor by means of a series of LEDs).
