Hardness Testers

Zentech offers a complete range of portable hardness testers for quick and convenient on-site hardness testing. Our hardness testing equipment range is comprised of portable instruments and a large number of probes and impact devices – opening up extensive application ranges – for every testing situation. In addition, our hardness equipment offers a quick and economical supplement to stationary hardness testing in the modern production process.
There are three physical methods of hardness testing recognized in the field: the static UCI (Ultrasonic Contact Impedance) method, the dynamic rebound hardness testing method, and the optical TIV (Through-Indenter-Viewing) method. The decision to utilize a specific method depends on the test problem.
The MIC 10 enables quick and convenient on-site hardness testing according to the UCI method (Ultrasonic Contact Impedance standardized according to ASTM A956 and DIN 50156). The diamond indent in the material’s surface is electronically measured and instantly displayed without using the cumbersome optical evaluation normally associated with conventional hardness testers.
By pressing a key, you can display your reading as a single value or as the active arithmetical average value of a hardness measurement set. Editing of erroneous single values, without having to interrupt the measurement set, is just as simple. Adjustable alarm thresholds show you critical measurement values both visually and with audiable alarms. The calibration parameters for measurements on low and non-alloyed steel are preprogrammed into the MIC10; however, the instrument can be easily and quickly recalibrated to other materials. Instrument operation can be customized for specific testing requirements: unnecessary functions can be inhibited, e.g. various hardness scales or the recalibration capability. This reduces key presses and simplifies operation.
