TKM-459CE combi controls hardness of following:

Carbon and structural steels as well as other fine-grained materials
Hard-surfaced items (cementation, nitride hardening, high frequency current hardening)
Heat-resistant, corrosion-resistant, stainless steels
Non-ferrous metals and alloys (cast iron, aluminium, bronze, brass)
Electroplated coating (chrome, copper, nickel, zinc, tin), overlaying
Items of complex configuration (gear teeth, shafts, pipes of any diameter, grooves, blind holes)
Thin-walled and small-sized items
Large items and heavy-duty equipment (gas pipelines, rails, construction elements)

Exploitation advantages

– Wide range of metals and alloys.

– Stable measurements with no impact from force and time of pressing the probe to surface.

– Low sensitivity to curvature and roughness of surface.

– Hardness measurement in hard-to-reach areas (position of probe has no impact on the results of measurement).

– Wide range of accessories.

Features of TKM-459CE combi

Impact-, dust- and water-proof housing.
Bright color display allows to make measurements at below zero temperature.
Signalization about exceeding of prescribed measurement threshold.
Unique statistical data processing system.
Fast calibration of device scales with one or two standard test blocks.
Flexible device memory for readings recording and analysis.
Programming of additional calibrations for scales of hardness tester with one or two standard test blocks.
Fast programming of additional scales with two to ten standard test blocks.

Hardness testers modes

Measurement mode	Readings	Using
By basic scales	Basic hardness units (HRC, HB, HV)	Hardness testing of the bulk of products
By additional calibrations to basic scales	By HRA, HRB, HSD scales and ultimate tensile strength	Hardness testing of high-alloy steels, special cast iron and nonferrous metals
By additional scales	Scales are programmed by the user	Special problems solving

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).
