What Our
Clients Say
Ron Ulbrich, Geiger Counter Pro
“The Radiation Alert Ranger® is a great value for those looking for a modern Geiger counter. I found that is simple to use yet includes many advanced functions if and when you want them without obstructing the simplicity…”
Judson Kenoyer, CHP, CIH
“I have used the Monitor 4 in courses that I teach radiation safety for close to 8 years. The students love it and affectionately call it the “Batman unit” because of its use in the movie The Dark Knight Rises. It is light-weight, sensitive, and quite often out performs some of the more expensive units from other companies that we use in a lab exercise…”
Neil Breslow, NDT Supply
“NDT Supply has been working with SE International since we started business in 2000. We have found them to be easy to work with, and a very reliable and responsive supplier. Questions and issues are always handled promptly and with a smile…”
Michael, Patriots Antiques
“Your Ranger changed how I run my business. It’s accurate, easy to use, and perfect for detecting uranium glass.”
Christopher Ulriksen, CSP, M.S.
“Great product, even better support. Quick replies, solid calibration—SE International is my go-to.”
Gregory Field, USMC/ARNG Ret.
“We used SE monitors in Iraq and Afghanistan—sandstorms, snow, even camel licks couldn’t break them. Only mortar fire did. I’ve trusted them ever since.”
