TQ-4Combi Plus – Combined hardness tester

Combined hardness testers

High-precision hand-held instrument equipped with brand-new software, designed for non-destructive testing of production quality. Targeted for use across a variety of industries including metallurgy, mechanical engineering, aircraft construction, shipbuilding, atomic industry, and oil and gas.

TQ-4Combi Plus combines the advantages of both UCI and Leeb methods for precise control of metals and alloys hardness.

Application

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

Operational advantages

  • Wide compatibility with various metals and alloys.
  • Stable measurements unaffected by force or time of probe pressing.
  • Low sensitivity to surface curvature and roughness.
  • Ability to measure hardness in hard-to-reach areas with consistent accuracy.
  • Wide range of compatible accessories for enhanced usability.

Features

  • Impact-, dust-, and water-proof housing for durability in challenging environments.
  • Bright color display for readability in below-zero temperatures.
  • Signalization alerts for exceeding prescribed measurement thresholds.
  • Unique statistical data processing system for accurate analysis.
  • Quick calibration of device scales using one or two standard test blocks.
  • Flexible device memory for efficient readings recording and analysis.
  • Programming capabilities for additional calibrations with one or two standard test blocks.
  • Fast setup of additional scales with two to ten standard test blocks.
