Rebound (Leeb) hardness tester TQ-3C
Rebound (Leeb) hardness tester TQ-3C 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.
TQ-3C controls hardness of following:
- All basic types of metals and alloys without additional calibrations (structural, tool, corrosion-proof, heat-proof, non-corrosive steels and alloys as well as alloys of nonferrous metals, castiron, aluminium, bronze, brass);
- Items with surface hardening and high frequency current hardening;
- Items of complicated configuration;
- Heavy and big items with rough surface.
Exploitation advantages
– Wide range of controlled metals and alloys.
– Low sensitivity to the curvative and roughness of surface.
– Monitoring of hardness change along the surface.
– Stable measurements independent from force and time of pressing the probe to the surface.
– Possibility of material identification in blank production.
– Control of “volumetric” hardness.
Features of TQ-3C
- Impact-, dust- and water- proof housing.
- Bright color 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.
