Physical Property Reference Materials
Physical property tests provide valuable information about the physical characteristics of environmental samples - such as air, water and soil – and play a crucial role in determining quality, suitability for various purposes, and potential impacts on ecosystems and human health.
We offer high-quality reference materials designed to support your environmental testing of physical properties: including pH, conductivity, turbidity, density, refractive index and colour standards. Discover our full portfolio of physical property reference materials below.
