The LMI G-whiz is a wireless device designed to measure closure velocity and wirelessly send readings to a PC or assembly information system.

The G-whiz is easily attached to the door using a vacuum cup. One press of the button will start the measurement. Once the door or sliding door has been closed, the velocity or work will be displayed on the LCD screen and a red/green LED will be displayed based on user-definable limits that are set within the G-whiz. The user can either re-test or wirelessly transmit the measurement data based on if the closure is fully latched or if a re-test is required.
