Environmental Management

Basic philosophy

On the understanding that the conservation of the global environment as the basis of human existence is the utmost priority across the world and that it is one of the most important concerns for the management, we promote environmental conservation activities with a view to the coordination between the socio-economic development and the global environment through sound business activities.

Environmental policy

  1. As a leading company of cutting-edge measurement technology, we promote technological innovation to reduce impacts on the environment through active development and distribution of measurement solutions that will contribute to SDGs.
  2. We endeavor to protect environment and prevent environmental pollution through continuous improvement of our environmental management system.
  3. We comply with all applicable environmental laws, regulations, agreements, and our voluntary management standards.

Environmental Management System

We have established an environmental management system based on our Environmental Policy and are making continuous improvements. In order to fulfill our social responsibility of protecting the global environment, we promote an environmental management system that complies with ISO 14001 and provide products and services in an environmentally conscious manner. In addition, we contribute to the realization of sustainable society and environment by complying with laws and regulations relating to products and services, and by reducing environmental impact throughout the life cycle of products.

Prevention of environmental pollution

Policy for handling mercury-containing products

We are taking the following steps to protect human health and the global environment from the artificial emissions of mercury and mercury compounds:

  1. Compliance with Minamata Convention on Mercury
  2. Continued activities to reduce the amount of mercury and mercury compounds contained in products handled

Environmental Data

We promote energy saving, resource saving, waste reduction, and recycling.
