Concrete Test Hammers W-M 250 / 350:

The W-M-250 Manual Test Hammer is the traditional instrument used for the non-destructive testing of hardened concrete. This easy-to-use instrument provides a quick and simple test for obtaining an immediate indication of concrete strength in various parts of a structure. The minimum verifiable strength is 1400 PSI (10 MPa).

The W-M-350 Recording Concrete Test Hammers 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.

Calibration Anvil Model W-C-7312 It is recommended that calibration of the concrete test hammers be checked regularly – usually after about 2000 strokes. The James Calibration Anvil (W-C7312) has been designed for just that purpose. The Calibration Anvil weighs approximately 35 lbs. (16kg) and should be ordered separately.
