  • Calibrated with NIST-traceable certificate and 1-year warranty

Radiation detection for field use

The Radiation Alert 4EC is a portable detector that reads dose rates from 0 to 500 uSv/hr. It is designed for professionals who need immediate radiation awareness during inspections, surveys or emergency response. The analog display shows CPM, mR/hr and uSv/hr without requiring menu navigation. A single 9 V alkaline battery is included and powers the unit for up to 2,000 hours.

Low power draw with analog simplicity

The meter draws very little current, so the supplied 9 V alkaline cell lasts for thousands of hours in normal use. There is no backlight or digital processor to increase consumption or generate audible noise. The analog needle responds instantly to changes in the radiation field without lag or refresh cycles. Operation is silent, making it suitable for quiet environments.

Replaces older analog survey meters

This unit replaces aging analog survey meters that have lost calibration or lack a NIST traceable certificate. The jump is worth it when a calibrated, ready-to-use instrument with a 300 keV beta sensitivity threshold is required for regulatory compliance. It is not suited for users who need data logging, digital readouts or energy-compensated response beyond the specified range.

Questions about this item

How do I install the 9V alkaline battery in the Radiation Alert 4EC, and what step do people often miss?

Open the battery compartment, insert the included 9V alkaline cell observing the polarity markings, then close the cover securely; the step users skip is verifying the analog needle rests at 0 uSv/hr before assuming the unit is ready.

What maintenance will the Radiation Alert 4EC need after the 2,000-hour battery run time is reached?

Replace the 9V alkaline battery and, if required by your quality programme, return the detector for NIST-traceable recalibration using the original calibration certificate as reference.

At what dose-rate does the analog display on the Radiation Alert 4EC stop indicating higher radiation levels?

The analog meter saturates at the maximum dose rate of 500 uSv/hr; any field above that value will still drive the needle to full scale without further distinction.
