General & Product Overview

 

Q1. What is a Brinell hardness tester machine?

Ans. A Brinell hardness tester is an industrial quality control device used to measure the hardness of metallic materials by pressing a hard carbide ball indenter under a specific test load (ranging from 250 kgf to 3000 kgf) into the specimen surface.

 

Q2. What is the standard price of a Brinell hardness tester machine in India?

Ans. The Brinell hardness tester machine price varies depending on automation levels (manual, optical, or computerized digital), load capacity, and features. Contact Multitek Technologies directly to receive an instant, accurate quotation based on your specific shop floor or laboratory requirement.

 

Q3. What is the difference between the Multitek BHN 3000-O and BHN 3000-TC models?

Ans. The BHN 3000-O is an optical Brinell hardness tester featuring a direct-reading optical device with 14x magnification. The BHN 3000-TC is a computerized/digital Brinell hardness tester equipped with a CCD camera system for automated image analysis, digital readout, and automated report generation.

Technical Specifications & Features

 

Q6. What is the maximum test load capacity of the Multitek BHN 3000 series?

Ans. The Multitek BHN 3000 series offers a test load range from 250 kgf up to 3000 kgf, adjustable in steps of 250 kgf to accommodate various metal thicknesses and alloy types.

 

Q7. What are the physical specimen dimensions supported by the BHN 3000-O?

Ans. The BHN 3000-O supports a maximum testing height of 380 mm and a throat depth of 200 mm, making it suitable for both small components and heavy industrial castings.

 

Q8. What motor and electrical power supply are required for the BHN 3000 machine?

Ans. The BHN 3000 operates on a 0.33 HP drive motor with a standard mains power supply requirement of 415V / 50 Hz / 3 Phase.

 

Q9. What size indenters are used in Brinell hardness testing?

Ans. Standard Brinell testing uses hardened steel or tungsten carbide ball indenters in sizes of 2.5 mm, 5 mm, and 10 mm, depending on the material type and applied load.

 

Q10. How does an optical Brinell hardness tester measure indentation?

Ans. An optical Brinell hardness tester uses an integrated optical measurement scope (such as Multitek’s 14x magnification lens) to measure the diameter of the ball indentation across two perpendicular axes, converting it directly into Brinell Hardness Number (HBW).

​

Digital & Automatic Hardness Testers

 

Q11. Why should I choose an automatic Brinell hardness tester over a manual one?

Ans. An automatic Brinell hardness tester automates the loading, dwell time, and unloading cycles while eliminating operator visual parallax errors during indentation measurement, accelerating testing cycles and improving repeat precision.

 

Q12. How does a digital Brinell hardness tester calculate HBW?

Ans. A digital Brinell hardness tester captures the indentation image using an optical sensor or CCD camera, automatically measures the average indentation diameter via software, and instantaneously displays the accurate Brinell Hardness Value on screen.

 

Q13. Can Multitek digital Brinell hardness testers export test results to Excel or PDF?

Ans. Yes, Multitek computerized and digital Brinell systems feature software capabilities that allow seamless export of test data, batch statistical reports, and calibration logs to Excel and PDF formats.

 

Q14. What materials are best suited for Brinell hardness testing?

Ans. Brinell testing is ideal for materials with coarse or non-homogeneous grain structures, such as cast iron, heavy steel forgings, cast aluminum, brass, bronze, and raw metals.

​

Multi-Functional & Combination Testers

 

Q15. What is a Brinell Cum Vickers hardness tester?

Ans. A Brinell Cum Vickers hardness tester is a dual-capability machine engineered to perform both heavy-load Brinell testing on raw casting materials and precision micro/macro Vickers testing on thin sheets or surface-hardened metals using a single unit.

 

Q16. What is a Brinell Cum Rockwell hardness tester?

Ans. A Brinell Cum Rockwell hardness tester allows industrial users to perform rapid Rockwell depth measurements alongside high-precision optical Brinell indentation testing without needing separate machines.

 

Q17. What are the advantages of a Universal (Brinell Cum Rockwell Cum Vickers) tester?

Ans. A universal hardness tester combines all three major hardness testing scales (Brinell, Rockwell, and Vickers) onto a single testing frame, saving lab space, reducing equipment capital costs, and expanding quality control testing options.

​

Calibration, Services & Maintenance

 

Q18. Why is NABL accredited Brinell hardness calibration necessary?

Ans. NABL accredited calibration guarantees that your Brinell hardness machine complies with ISO/IEC 17025 standards, ensuring measurement accuracy, traceablity to national standards, and compliance during customer audits.

 

Q19. How often should a Brinell hardness tester machine be calibrated?

Ans. Brinell hardness testing machines should undergo full indirect and direct calibration at least once every 12 months, or sooner if the machine undergoes major maintenance or moves location.

 

Q20. Does Multitek Technologies issue NABL calibration certificates?

Ans. Yes, Multitek Technologies operates an in-house NABL accredited calibration laboratory and provides certified calibration reports accepted across global industries and regulatory bodies.

 

Q21. What is included in a Brinell hardness testing machine calibration certificate?

Ans. A calibration certificate details load accuracy verification, indenter condition inspection, optical measuring scale accuracy, environmental testing conditions, expanded measurement uncertainty, and traceability details.

 

Q22. What daily checks should be performed on a Brinell hardness tester?

Ans. Operators should perform daily verification checks using an ISO/ASTM compliant standard reference hardness block before starting any testing batch.

 

Q23. Does Multitek Technologies provide Annual Maintenance Contracts (AMC)?

Ans. Yes, Multitek offers comprehensive Annual Maintenance Contracts (AMC) covering routine preventive maintenance, mechanical tune-ups, hydraulic/optical alignment, and emergency engineer visits.
