​Description de Honeywell Granit 1991

• With a best-in-class 3 meter (10 foot) drop, Granit™ XP is engineered to keep on
  working after the impact of drops from loading docks, forklifts and picking trucks.
  The 1 meter (3.3 foot) tumble test indicates lasting durability with daily knocks and
  drops from workstations or waist height. A best-in-class 7,000 tumble specification
  ensures Granit scanners are ready to work long-term in demanding environments.
  Field feedback shows that the scan window is a high-frequency failure point for
  scanning devices in the industrial environment. Granit scanners are designed with
  a small, deeply recessed, scratch- and impact-resistant window to prevent these
  failures. This is a critical sealing component ensuring dust and moisture do not enter
  the case and degrade scanning performance or cause premature failure. The Granit
  solution ensures its IP67 sealing remains intact, even under harsh treatment.
