"We purchased the TKM-359M Hardness Tester in 2017. Around twenty thousand impacts were made along the period of use. The device was an ideal choice:

- it is easy to use (charging of the spring is quite simple) as it is reliable;

- the device makes the recounting automatically and immediately displays the reading of the hardness value (after excluding all incorrect results);

- high accuracy of the results;

- it is compact, easy to carry around, and the kit comes with a strap to hang around the neck and keep the device on the chest;

We wish that the Shore Hsc (Hsd) could be included in the scales list and that limits of absolute error when using the Shore Hardness scale were indicated in Table 1."

Chief Executive Director, S.A. Tikhonov
