The RadCompass is a unique instrument, offering a compact, easy-to-use, low cost solution for radioactive source localization. This directional survey meter displays both gamma dose rate and 360º directional information and is an ideal tool for first-responders, military personnel, and industrial radiation surveyors.

The RadCompass uses an array of shielded radiation sensors to locate radioactive sources. The design supports the rapid localization of radioactive sources, even in high radiation fields. The multi-element sensor provides continuous directional information and does not require the user to scan the system from side to side or up and down in order to determine source location.

The ‘Mode’ button allows the user to easily switch pre-set counting times, as desired. The dose rate units can be easily toggled to display in µSv/h or µRem/h.
