Abstract: A handheld digital measuring device, method and kit therefore are provided. The device includes first and second elongated, substantially flat blade members having proximal and distal ends. At a proximal end thereof, the blade members are fixed to and extend from a housing. The first and second blade members are movable relative to one another in an opposing manner to provide a defined and measurable distance between the distal ends of the first second blade members. Optionally, the device may have a photosensor for sensing a dimension of the distance between the distal ends of the blade members and a microcomputer responsive to photosensor signals for transmitting the distance to a display device. The device may also comprise a spring-loaded pneumatic mechanism for urging the blade members apart. The device is preferably handheld and includes buttons or a keypad for controlling operation thereof.
