I don't know what model this is but i included measurements. there are 2 buttons on the side. the display is very heavy duty and made entirely of metal. made in the USA. i don't really know anything else about this, it wasn't mine it came from an auction. seems to be in good condition and fully functional but im not exactly sure what features it has or how to set it.
