About the Unitech MS852 LR / MS852B LR (2D)

The Unitech MS852 LR series reads barcodes from 7.6 cm up close to as far as 21 m, so warehouse staff can scan labels on high racks and pallets without a ladder. The MS852 LR is corded over USB; the MS852B LR is cordless with dual-mode Bluetooth, reaching up to 100 m from its cradle and storing codes in memory when out of range.

It reads 1D and 2D barcodes on labels and screens, plus OCR and DotCode. It is IP42 rated, tested for 1.8 m drops to concrete (2.2 m with the protective cover) and has a trigger rated for 10 million presses. A louder beeper and brighter LEDs help in dark aisles.
