The United Testing Tru-Blue II is a bench-top Rockwell hardness tester in 10, 14, 18 and 20 inch vertical test heights - certified to ASTM E18 and ISO 6508, in service at NADCAP-approved heat treatment, fastener and aerospace component manufacturing facilities.
Fully compatible with our Scrub Abrasion & Washability Tester, the MEK Tester Pro Accessory allows users in R&D, quality control and product development to evaluate the chemical resistance, durability and performance of their coatings.
The Can Holder accessory is a useful tool to allow users be able to hold a wide-range of cans or cylindrical samples with their Scrub Abrasion and Washability tester. Ideally combined with the MEK Tester, so users can carry out solvent and chemical resistance of their can’s coatings.
Carbide ball indenters:1/16, 1/8, ¼ and ½ inch. 2.5, 5 and 10mm.
Rockwell diamond indenters: Scales A, C, N and C/N combo indenters.
Several accessories are available for United's True Blue II Hardness Tester.
Hardness Anvils for the True Blue II Rockwell Hardness tester.
The Tru-Blue II mobile stand provides a sturdy base and makes it easy to move the tester from one location to another.
Our Cylindrical Bend Test is designed to measure the elasticity, elongation and adhesion of a paint film at bending stress on metal panels. Our easy-to-use bend test equipment offers straightforward and reliable mandrel testing.

Coating thickness, adhesion, and curing quality directly affect corrosion resistance and product compatibility. Insufficient coating or improper curing can lead to blistering, metal exposure, or flavor contamination. Conducting routine enamel rating, adhesion, and curing tests helps maintain coating integrity and ensures longterm product protection.
Double seam performance is influenced by body hook length, cover hook formation, overlap, tightness, and material thickness. Variations in seaming pressure, tooling wear, or can/end alignment can lead to defects such as false seams, wrinkles, or cutovers. Using calibrated seam inspection tools and standardized measurement procedures ensures consistent seam quality across production.
There are a huge number of different testing options for metal packaging we can help you with, here are just a few of the most common:
