PORTABLE HARDNESS TESTERS 

Portable high precision hardness testers TQ intended for quick measuring of metal items hardness in laboratorial, manufacturing and field conditions.

The device performs non-destructive quality control of products in metallurgy, mechanical engineering, aircraft construction, nuclear industry, oil and gas industry.

Portable Hardness testers is intended to be used for hardness measurement of carbon construction steels in basic hardness scales — Brinell (HB), Rockwell (HRC), Vickers (HV), Shore (HSD).

TQ CONTROLS HARDNESS OF FOLLOWING:

• Carbon and structural steels as well as other fine-grained materials
• Heat-resistant, corrosion-resistant, stainless steels
• Non-ferrous metals and alloys (aluminium, bronze, brass)
• Various types of cast iron
• Items with surface-hardened layers (cementation, nitride hardening, high frequency current hardening)
• Electroplated coating (chrome, copper, nickel, zinc, tin)
• Items of complex configuration (gear teeth, shafts, pipes of any diameter, grooves, blind holes)
• Thin-walled and small-sized items ` Heavy and big items with rough surface

UCI HARDNESS TESTER TQ-4C
