Mash Project UCI Hardness Tester
TKM-459CE-UCI
The TKM-459CE uses a Vickers diamond indenter at low loads (1,5 or 10 kg,) for virtually non-destructive hardness measurements. The TMK-495CE-UCI tester can be used for applications such as:
| | - Finished machined parts such as crankshafts, gears, etc. (5 kg probe)
- Hard chrome plated shafts (1 or 5 kg probe)
- Surface hardened parts (1 or 5 kg probe)
- Hardness profile of pipeline and pressure vessel welds (10 kg probe)
|
The TK-495CE-UCI can be used in any position and it finds its place on the jobsite, factory or laboratory.
Features:
| | - Intuitive graphic interface
- Bright color graphic display that allows measurements at below zero temperature and this display stays bright in all lighting conditions
- Statistical data processing system
and averaging of readings - Special calibrations for non-standard materials can be easily made using one or two known hardness samples
- Memory for recorded measurements, readings, and their analysis
- Stable readings independent from force and time of load applications
- Minimally affected by curvature, thickness, and weight of the test piece
- Hardness measurement in hard-to-reach-areas
- Very small control area from .040in (1mm)
- Measure in keyways and blind holes from 0.2in (5mm). Which is not possible with other types of hardness testers
- Microscopic indentation does not ruin most highly finished parts
|
TKM-459CE Applications:
| | - Carbon and structural steels
 - Hard-surfaced items (nitride hardening, high frequency surface hardening)
- Heat-resistant, and corrosion-resistant, stainless steels
- Non-ferrous metals and alloys (cast iron, aluminum, bronze, brass)
- Electroplated coating (chrome, copper, nickel, zinc, tin) plated
- 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)
|
Testing Requirements:
| | - Items heavier than 2.2lb (1kg) and thicker
than 0.08in (2mm) need no additional preparation - Items lighter than 2.2lb (1kg) should be fixed in a vice clamp or on a support plate by fixing paste
- Items thinner than 2mm should be fixed in a vice clamp or on a support plate by fixing paste
- Roughness of controlled surface providing best measurement accuracy is 1.6 RA

| Hardness Tester Modes |
| Measurement Mode | Readings | Application |
| 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 problem 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 rejection of garbage/incorrect measurement
- Comparison of results of measurements in the series (the comparison charts on the display of the hardness tester)
