Three-function data logger. Jack C. Thompson and Roger Marin, an electronics engineer, have formed Pier Point Instruments to manufacture and market their Data Logger Model DL-400, which they have developed over the last three years. The ad says the prints can be safely displayed under normal viewing conditions for over 300 years without any change. Shipped flat, they can be assembled at the bookshelf in 15 to 60 seconds. Measuring devices are supplied upon request.
Cost is much less than that of handmade boxes, and they take up very little additional shelf space.
