Wilson BH3000

The Wilson BH3000 is a durable, 30 kN (3000 kgf) Brinell hardness tester that is ideal for wide range of Brinell loads from 62.5 kgf – 3000 kgf. Designed with rugged construction to withstand harsh environments, the reliable BH3000 Brinell hardness testing machine combines high rigidity and closed-loop load cell technology to ensure accurate and safe load applications. Key features of the BH3000 Brinell hardness tester include a clamping device for securing parts to the exchangeable anvil, an easy-to-use user interface to set up and operate the tester, a built-in keypad calculator that accurately presents HB hardness values, and an LCD screen.

This hardness tester has a wide Brinell scale load range of 612N – 29.42 KN (62.5 kgf – 3000 kgf.) The LCD screen displays statistics per test series, results, and language settings. The display also features an integrated hardness calculator, Brinell hardness diagonals, value, statistics, and conversions.

Wilson VH1102 & 1202

The VH1102 and VH1202 micro hardness tester machines designed for both Knoop and Vickers offer a versatile, affordable, and reliable solution for accurate micro-hardness testing, both for quality control and for metallurgical research applications. The VH1002-series allows it´s operator to take measurements using the digital eyepiece in standalone mode or by using an optional integrated high-resolution camera and the powerful DiaMet™ software.

Buehler’s microhardness testers are equipped with a four position turret which includes one indenter position as well as a 10x and 50x objective. The turret offers either four or six objective slots, allowing you to fit all the magnification power for your application. The standard 10x and 50x objective can be extended with an 100x objective, thus allowing for a total magnification of up to 1000x.
