Two sales aides were developed to demonstrate the superior quality and design of hand tools.
The unit shown was for testing the squeezing capabilities of hand tools. The display, (shown in the upper right of the picture) was a series of LED's.
As the pressure increasing, an increasing number of LED's illuminated.
The display, electronics, mechanics and sensors were built into portable units for trade shows.
A similar unit was built for demonstrating the torque capabilities of various hand tools.
