Environmental problems such as global warming and desertification are great concern worldwide, and quick approach to properly dispose of industrial waste and improve working environment is needed. With this background in mind, KMTL analyzes the quality of water, air, and soil to national and prefectural laws and regulations. We also perform water quality control and inspection at power plants.

 KMTL measures various materials to determine their thermal properties (thermal constant, thermal expansion ratio, melting point, glass point, and weight change), as well as the conductivity, grain-size distribution, density, viscosity, and optical property (reflectivity and transmissivity). Oil samples such as lubricants are also analyzed for their properties (neutralization value, kinematic viscosity, hue, water content, and heat value).
