New Ruggedized Case Silicon Rubber Bumper and modernized key pad. Note: Silicon case color may vary from the red shown in the images. The software and features are the same as the original and very popular TCM-U2 ( black case seen in videos ) only the case and keyboard are different. 3 year warranty on probe and tester.
Closest competitor is $4895!!!!! Our device has the same spec and accuracy as the top priced models selling for $6000 and more. This tester has the option to add a D (universal) rebound type test probe and firmware activation which turns the device in to a TCM-UD2. This means you get the best of both technologies, UCI and Rebound. The D type is ideal for Non Ferrous materials, coarse grained parts like cast iron etc. that are not suited to UCI testing. Can be added for only $650

The UCI Hardness Tester TCM-U2 operates according to the Ultrasonic Contact Impedance (UCI) method of hardness testing, and is standardized according to ASTM A1038 . The basic operating principle is that hardness is measured by detecting the frequency shift of a longitudinal oscillating rod fused to a Vickers diamond indenter. The diagonals of the indentation are not optically measured as with traditional Vickers tests, so there is no need for cumbersome optical evaluation with a microscope. Instead, the indentation area is electronically detected by measuring the frequency shift. The shift is proportional to the size of the indentation. This method enables quick and easy measurement: position probe, press to apply the test load, and read off the hardness value. TCM-U2 probes use a Vickers diamond indenter that gives you the precision to position it on a tiny point. Indentations produced by the TCM-U2 are much smaller than equivalent Rockwell indentations, making this one of the least destructive portable hardness testers available. These attributes make the TCM-U2 well suited to these typical applications: - Heat affected zone (HAZ) of welds - Hardness progression curves - Fine-grained materials - Heat-treated materials - Thin layers and coatings - Surface hardened parts - Thin wall pipe - Small parts
The advantages of ultrasonic contact impedance hardness tester TCM-U2:
Examples of parts that are most suited to this type of portable testing and cannot be done at all or as easily by other portable test methods are.
