COMBI hardness tester TQ-4Combi
COMBI hardness tester TQ-4Combi – portable precision device with brand-new soſt ware.
Device is intended for non-destructive testing of production quality in metallurgy, mechanical engineering, aircraft, shipbuilding, atomic industry, oil and gas industry.
Applying TKM-459CE combi you receive all advantages of UCI and Leeb methods of metals and alloys hardness control.
TQ-4Combi 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 TQ-4Combi
- 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.
