Found at my local Aldi in Sutton Coldfield at the till amongst other reduced to sell items. This is from Welby and is model BPM 2007. Contains the usual readings plus 60 storage settings for those who need them. Powered by 2 AAA batteries (supplied), autopowers off for the forgetful and comes with a hard white case.
No link to the offer, unfortunately, as this is instore only, but have a pic from ebay from somebody selling the same product.
