MS840B | Bluetooth Laser Scanner (1D)

The MS840B rugged Bluetooth barcode scanner is a premier wireless barcode scanner ready to be deployed in the challenging work environments or warehouse, light industrial and retail applications.

The MS840B features Unitech’s Mantis decoder for fast and aggressive reads, while its reliable Bluetooth connection provides 300 feet of wireless freedom.

The MS840B repels dust and water, protecting the technology within. It can also withstand falls of up to 6 feet to concrete.

This Bluetooth barcode scanner has a cradle accessory that can mount to a desk or wall (though the device is fully functional without a cradle). If you misplace the device, pressing the locate button on the charging cradle allows the scanner to emit loud beeps so you can find it quickly. You can also sync up to three MS840B scanners to a single cradle for added convenience and communication.
