Sealed against dust and water
Every device is rated at least IP65: fully dust tight and protected against water jets from any direction. Most go further. An IP67 or IP68 rating means the housing survives immersion, not just a light shower, which is the difference between a tablet that survives a downpour and one that survives being dropped in a puddle. None is rated IP69K for high pressure jet washing, so wipe them down rather than hose them.
- Gasket-sealed ports and a sealed speaker membrane
- Removable batteries on the A6, A8, WH6 and W10, so a charged spare takes over mid shift
- The A6, A10 and WH6 are rated from −20°C, so they start on a frosty morning
