We provide testing services to certify product and materials compliance, support quality control, and ensure the health and safety of workers and their environment. We provide assistance for clients who are not sure what tests they need. Our accredited materials characterization laboratory is the foundation of all the services of RJ Lee Group provides, including standardized testing for compliance, industrial hygiene and environmental analyses, quality control, and materials research and development.
RJ Lee Group maintains a visible and respected reputation within the legal community, having offered scientific support in civil litigation matters for nearly 30 years.
From our core business of providing scientific solutions to our clients, we have developed innovative products. Some are produced internally, and some have arisen from partnerships with other research organizations.
For example, we build lab software solutions to help manage and streamline your labs data, and environmental testing products for a variety of applications.
Other products we create count particles and help keep the air and environment safe.
