particles, which ensures an extreme rigidity and

temperature stability for unparalleled precision

which means that once you obtain a value of

100% on a hard flat surface, you have the

guarantee that the device is fully calibrated. the

calibration is very stable, and till now, the

plastic cover and clean any fruit juice on the tip

and cover with soap and water
