Programmable hardness test time
Eureka! D2020 Density is based on Archimedes’ principle: the buoyant force on a sample immersed in water equals the weight of the water it displaces.
Fully automated operation keeps results repeatable and frees your operator for other work in the lab.
Hardness measures how well a material resists permanent indentation under a specific force, using methods Albert F. Shore developed in the 1920s. Both D2020 Hardness versions deliver highly repeatable measurements on rubber and polymer parts.
D2020 instruments meet the major international density and hardness standards, so one platform covers your specifications worldwide.
