Panasonic has announced a more "value" edition of its Toughpad FZ-M1 Windows 8.1 tablet for businesses and professionals that require the ruggedness, but for less of an outlay.

The 7-inch tablet has a dual-core Intel Celeron N2807 processor rather than the Core i5 vPro in the fully fledged version. However, the new chipset offers long battery life and is suited to mobile devices.

It also comes with 2GB of RAM (4GB optional) and a 128GB solid state drive. The tablet is fanless and weighs 540g. Even with the IP65 protection, it is 18mm thin. And the LCD screen has a resolution of 1280 x 800.

Other configurable options include 4G mobile broadband, GPS and vehicle pass through antenna. A business expansion module can add True Serial, LAN, NFC, a smartcard reader, 1D/2D barcode reader, UHF RFID and/or battery hot swap capabilities. An 8-megapixel rear camera can also be added - there's a 2-megapixel front-facing webcam built-in.

It already includes a full size USB 3.0 port, microSD card slot, headset and microSIM slot. Battery life is claimed to last up to eight hours.

The Panasonic Toughpad FZ-M1 Value will be available from June for £739.
