High precision hardness tester TKM459CE intended for quick measuring of metal Items hardness In laboratorlal, manufacturing and field conditions. The TKM-459CE works on the principle of "Ultrasonic Contact Impedance": The piezoelectric crystal causes the rod in the probe to vibrate longitudinally. The Vickers diamond at the lower end of the rod Is pressed by a spring Into the work piece surface. Depending on probe choice. this is done with the thrust of 10. 50 or 100 Newton.

Measurement
Hardness testing on fine-grained, weld joints thin-walled materials and alloys, carbonaceous and structural steels Items with surface-hardened layers such as cementation, nitride hardening, high frequency current hardening Heat-proof, corrosion-proof, non-corrosive steels. Plated coating (chrome), overlaying, Items of complicated configuration. Device Is Intender) for non-destructive testing of production quality in metallurgy. Automotive, Tubes & Pipes. Gear. Bearing , mechanical engineering, aircraft, shipbuilding, atomic industry, oil and gas industry.

TKM-459CE controls hardness of following :
• Carbonaceous and structural steels
• Items with surface-hardened layers such as cementation, nitride hardening, high frequency current hardening
• Heat-proof, corrosion-proof, non-corrosive steels
• Plated coating (chrome), overlaying
• Items of complicated configuration

Exploitation advantages :
• Stable readings independent from force and time of pressing.
• Easy measuring in hard-to-reach areas.
• Ultra-small control area (from 1 mm).
• Control in slots and blind holes from 5 mm (not provided by rival devices).
• Invisible print on mirror-surface.
• Low sensitivity to the curvative of surface, thickness and weight of product.

Features :
• Impact-, dust- and water-proof housing.
• Intuitive graphic interface.
• Bright color graphic 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 & 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 by 2 or less standard test blocks.
• Fast programming of additional scales by 2 to 10 standard test blocks.
