  • Hardness Testers

    PCE Instruments

    The hardness tester products you will find at PCE Instruments (PCE) are used for determining surface hardness. Each hardness tester uses a standard method of measurement. The measuring principles of most hardness tester devices are based on either the penetration of a diamond indentor into the material being tested or a calculation related to the force of the rebound after striking the tested material. However, material hardness can also be measured accurately through ultrasonic testing. Each hardness testing method has its benefits and will allow for the precise measurement of material hardness in accordance with the technical specifications of the hardness testing instrument.

  • Portable Hardness Testers

    NovoTest

    The UCI hardness measuring method complies to ASTM A1038.The ultrasonic contact impedance (UCI) probe is purposed to be used for hardness measuring in the case of the testing area minimal thickness (from 1 mm), objects of complex surface shape, and for measuring surface hardened layers hardness.This method is very fast and easy: place the probe on the tested object surface, press the probe with the required effort to the surface and save the hardness value, shown on the display of the device. Small size diamond indenter allows measuring hardness value of all items, which are thicker than 1 mm. The UCI method of hardness testing is the least destructive because the hardness tester NOVOTEST T-UD3 with UCI probe leaves much smaller prints (imprints) than the majority of bench hardness tester would. That’s why a portable hardness tester with UCI probe is the best choice.
