EnviroMentor has both the measuring

instruments and the expertise

EnviroMentor AB is a young, skills-based company, yet is also one of the

oldest in its field. All of our measuring instruments have been developed

in extremely close cooperation with researchers at Chalmers Institute of

Technology in Göteborg. EnviroMentor AB is wholly owned by Radians

Innova AB, a company which in turn is owned by two of Sweden’s most

powerful financial institutions. This combination of excellent skills and

good financial resources provides us with the potential to carry on continual

product development, keeping pace with the latest discoveries made by

researchers. You can find out all about our current range of measuring

instruments for the electrical environment from EnviroMentor’s various

product sheets. Please do not hesitate to contact us if you would like further
