EnviroMentor has both the measuring
English
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
