Click on the links below to see what we have to offer. If you have questions or do not see exactly what you are looking for, please contact us directly.

Survey meters are portable radiation detection and measurement devices used to detect and measure external or ambient ionizing radiation fields. They are also used detect and monitor personnel, equipment and facilities for radiation and radioactive contamination.

Most instruments have been designed and developed to be hand-held, battery powered and easy to deploy. Meters can be fully integrated with probe and processing electronics in one housing to allow single-handed use, or they can have separate detector probes and electronics housings, joined by a signal cable.

The end user should have an understanding of the types of radiation that could be encountered so that the correct instrument is used. Many instruments are sensitive to more than one type of radiation; alpha and beta, or beta and gamma, for instance, and the operator should be aware of the differences. Ideally, the user will have the skills necessary to not only operate the instrument, but also to interpret and comprehend the results.
