Feedback for TKM-359M hardness tester (OOO "PromTECK" - Novotroitsk, Russia)
"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."
