Combined Hardness Tester NOVOTEST T-UD3
Industrial inspection equipment
Overview
Combined hardness tester combines two methods of measuring hardness: Ultrasonic Contact Impedance (ASTM A1038) and Leeb (ASTM A956). This makes the device the most versatile portable device as it can be. Material verification supports production quality assessment component acceptance and heat treatment evaluation across engineered metal parts helping inspectors confirm conformity before service deployment.
Combined Hardness Tester NOVOTEST T-UD3 is configured with Small indenter imprint (suits for mirror surfaces of shafts necks blades gear teeth etc.), Measuring surface hardened layers hardness, and Wide range of hardness testing to support reliable day-to-day inspection work in demanding operating conditions.
Key technical details include Measurement Methods: UCI + Leeb, Hardness Scales: HV, HB, HRC, HRA, HRB, HS, Measurement Range: 200-960 HV (UCI), 170-960 HLD (Leeb), and Accuracy: ±3 HV (UCI), ±6 HLD (Leeb), helping teams evaluate fitment, access requirements, and inspection coverage before deployment.
This product is suited to applications such as Quality control in manufacturing, Heat treatment verification, and Weld hardness inspection, where repeatable imaging, measurement, or defect detection performance is important.
