Description
Ultrasonic Contact Impedance (UCI) probe digunakan untuk mengukur nilai kekerasan pada benda berukuran kecil, objek dengan dinding tipis, bentuk yang kompleks, serta untuk mengukur kekerasan lapisan permukaan yang dikeraskan (surface hardened layers).
Alat ini dilengkapi dengan built-in camera yang memungkinkan pengguna untuk mengambil foto objek pengujian dan menandai area yang diuji dengan nilai kekerasan yang sesuai. UCI Hardness Tester NOVOTEST T-U3 memiliki sealed housing dengan strip pelindung karet, sehingga sangat ideal untuk digunakan di bengkel (workshop) maupun kondisi lapangan dengan kelembapan tinggi, berdebu, dan lingkungan ekstrem lainnya.
Selain itu, hardness tester ini memiliki frost-resistant display yang memungkinkan perangkat tetap berfungsi optimal di musim apa pun dan di zona iklim mana pun di dunia. Perangkat ini juga dilengkapi dengan PC software yang memiliki antarmuka nyaman dan intuitif.
Metode UCI untuk Pengujian Kekerasan
Metode pengukuran kekerasan UCI ini telah memenuhi standar ASTM A1038. Ultrasonic Contact Impedance (UCI) probe dirancang khusus untuk pengukuran kekerasan pada area pengujian dengan ketebalan minimal (mulai dari 1 mm), objek dengan bentuk permukaan yang kompleks, serta untuk mengukur kekerasan pada surface hardened layers.
Metode ini sangat cepat dan mudah dilakukan:
Letakkan probe pada permukaan objek yang diuji.
Tekan probe ke permukaan dengan tekanan yang diperlukan.
Simpan nilai kekerasan yang muncul pada layar perangkat.
Penggunaan diamond indenter berukuran kecil memungkinkan pengukuran nilai kekerasan pada semua benda yang memiliki ketebalan lebih dari 1 mm. Metode pengujian kekerasan UCI ini merupakan metode yang paling tidak merusak (least destructive), karena hardness tester NOVOTEST T-UD3 dengan UCI probe meninggalkan bekas tapak (imprints) yang jauh lebih kecil dibandingkan mayoritas bench hardness tester pada umumnya. Itulah alasan mengapa portable hardness tester dengan UCI probe adalah pilihan terbaik untuk kebutuhan Anda.
Features
- Hardness measurement of any mass products with a thickness more than 1 mm – inaccessible to the dynamic (Leeb) hardness testers (small parts, thin-walled structures, pipes, tanks, steel sheets, articles of complex shape, hardness control of metal coatings, etc.)
- Measuring the hardness of the surface hardened layer
- Small imprint after measuring (mirror surfaces of shafts necks, blades, gear teeth, etc.)
- Wide range of hardness testing
- Various measurement modes
- Calibration of any scale in any range
- Convenience and ease for measurement
- Optimized number of buttons
- Large full color graphic display with bright back-lighting
- Calibrations stored in memory of probe

- Internal memory and communication with PC
- New, intuitive menu with tips on the buttons
- Optional wireless mini printer
- Water resistant case
- Rubber protected bumper
- Has different operating modes:
Graph – the mode of building of graph Histogram – the mode of building of histogram Statistics – the mode of statistic Smart – the mode of filtering of incorrect measurements
Available Option
- Additional UCI (10N, 50N, 98N) probes can be purchased. Also, after the purchase if will be needed, user can order dynamic Leeb probe (D, DC, DL, C, D+15, E, G) with activation code and will get combined hardness tester with two probes (Leeb+UCI).
- Different colors of rubber bumper protected case

- Batteries
- Chargers
- Hardness tests blocks
- Portable grinding machine
- Case for hardness tester
UCI Hardness Tester NOVOTEST T-U3 can be equipped with three types of UCI probes:
| Model | Load | Features | Main applications | |
| UCI U1 (98 N) | 98 N(10 kgf) | The main type of probe for solving most problems of hardness measurement. 10 kg load is to be applied for measurement (set automatically by the probe). Low requirements for surface cleanliness. | – Heat-treated and cemented details.- Measuring in grooves, on teeth, on radius surfaces.- Measurement on the blades, on the internal surface of the pipes, openings. | |
| UCI U1 (50 N) | 50 N(5 kgf) | The main probe type for the most tasks of hardness measurement. 5 kg. load is to be applied for measurement (automatically controled by the probe). Average surface cleannes requirements. | – Heat-treated and cemented parts, for example, shafts, turbines, gears, teeth, welds, heat affected zones.- Measuring in grooves, on teeth, in grooves, on radius surfaces.- Measurement on the blades, on the internal surface of the pipes, openings. | |
| UCI U1 (10 N) | 10 N(1 kgf) | The reduced load probe is designed to measure the hardness of material with increased requirements to the print size (polished surfaces), to measure the hardness of surface hardened layers. 1 kg. load is to be applied for measurement (automatically controled by the probe).
More sensible to the surface cleanliness, in comparison with U1 (50 N). | – Nitrided and cemented surface layers of molds, stamps, stamps, thin-walled parts.- Bearings, lateral surfaces of saws teeth.- Measurement of hardness of hardening coatings.- Measurement on the blades, on the inner surface of the pipes, inside the holes. |
