High precision hardness tester TKM-359CE intended for quick measuring of metal items in laboratorial, manufacturing and field conditions.
Device is intended for non-destructive testing of production quality in metallurgy, mechanical engineering, aircraft, shipbuilding, atomic industry, oil and gas industry.
Hardness tester functions by Leeb method.
mpact-, dust- and water- proof housing;
Intuitive graphic interface;
Bright color graphic display allows working at below zero temperature and stays bright at any lighting;
Signalization of exceeding of prescribed readings threshold;
Unique system of statistic data processing and averaging of readings;
Fast adjustment of readings and programming of additional calibrations to basic scales by 2 or less standard blocks;
Flexible device memory for recording of readings and their analysis;
Programming of additional scales calibrations of hardness tester by 2 or less standard test blocks;
Fast programming of additional scales by 2 to 10 standard test blocks.
Requirements to Controlled Item:
Items heavier than 5 kg and thicker than 6 mm need no additional preparation.
Hard items (eg tubes) with awaited hardness from 90 to 250 HB and thicker than 4 mm need no additional preparation.
Other items should be fixed on a support plate by fixing paste.
Roughness of controlled surface providing best measurement accuracy depends on a probe.
The parameters of the statistical processing of measurements
Maximum, minimum, mean value, standard deviation from the mean.
The average deviation from the values set by a user, results are more/less the values, the maximum deviation in the large/smaller side of the value.
Number of results outside the upper/lower limit of range (user specified), maximum deviation from the upper/lower border.
Automatic garbage results, incorrect measurement.
Comparison of results of measurements in the series (the comparison charts on the display of the hardness tester).
