In August 2023 NZI took ownership of a new model 3000E Mastersizer. This is a significant investment in replacement equipment for NZI to retain our Quality certification.
The Mastersizer uses the technique of laser diffraction to measure the particle size and particle size distribution of materials. It does this by measuring the intensity of light scattered as a laser beam passes through a dispersed particulate sample.
The NZI lab run tests on our clay slip using the Mastersizer on a daily basis. This ensures that the product produced from the clay will perform to the standard expected for strength and reliability and continues to meet our quality standards.
