Automated samplers for consistent cement sampling

Without correct sampling, then preparation and analysis are compromised. It has been calculated that 80% of quality errors can be sourced to poor sampling, making the need for fit-for-purpose samplers paramount. Our range of specialised sampling devices service all the routine sampling programs across the cement plant.
