S.E. International Digital Radiation Detectors are compact, durable, and easy-to-use and include an assortment of features and accessories. Most models detect Alpha, Beta, Gamma, X-Ray in a single unit. LCD display with back light, multiple units of measurement to choose from, timed counts, and programmable alerts are only a few of the features available.
Each radiation detector comes with a ruggedized overlay to protect the instrument from drops and scratches. Free software and apps to expand the capabilities make reporting simple. Track exposure, program custom alerts, download your collected readings, and change the preferences on your radiation detection instrument. Users can collect, save, share, and analyze data.
There are 5 models to choose from:

Monitor 200 Features The Monitor 200 measures alpha, beta, gamma, and x-rays. Its digital display shows readings in your choice of CPM, CPS, μSv/hr, mR/hr, or in accumulated counts. It has a digital, easy to read backlit display, a red count light, and a beeper that sounds with each count detected. This unit also includes an adjustable timer and a loud, customizable alert. With the Free Radiation Alert Observer BLE app from the Google App Store, you can display the readings from your detector, label sample readings and descriptions, take timed counts, append GPS data and send your saved survey file. Alarms set on the instrument will also activate on your Android device. The Free Observer USB software (Windows® only) reads in Total Counts, CPM, µR/hr, mR/hr, CPS, µSv/hr, and has the ability to collect and log data, set alarms, set timed counts, set the calibration date and settings, and generate reports.
