Customer Reviews
The touch screen micro vickers hardness tester has been installed a few weeks ago, everything is OK. Thanks for your advice and excellent service.

—— Mr. David Chambers

Thanks for the fast delivery and our customer is very satisfied for the rockwell hardness tester, and hope more orders soon.

—— Neil Renato

After we visited the customer, they finally decided to purchase Brinell hardness tester iBrin-413Z, now we have installed the unit at customer’s site,

—— Fermin Lee

Thank you for the indenters (diamond  cone 120 degrees). We recently got it and already tested it. Indenters  are good as we expected. 

—— Dalius Skinulis

The Measurements are good for Brinell Tester HBST-3000.

—— Sun Chull Kim

Hey, the hardness tester iVick-484ST was installed last week and works well, thanks for the professional support.

—— Sabinian Smith
