Description
The W-M-350 Recording Test Hammer gives you the same quality as the W-M-250 but with the added feature of a built-in automatic chart recorder. Every test you take is automatically recorded as a bar chart on a paper strip. This creates a field record to verify your findings. In addition to this paper record, you can see each test as it happens through the large easy to read window. The W-M-350 comes with two rolls of paper, each with a capacity to record over 4000 tests.
