Model 907

Model 907Radiation Survey Meter Alpha, Beta, Gamma, & X-Ray

The palmRAD 907 nuclear radiation monitoring meter provides multiple monitoring and surveying options in an easy-to-use handheld device. It measures alpha, beta, gamma, and x-ray radiation which can be displayed in rates and total counts. The user can switch between mR/hr, Svi cpm, and total counts.

This model would function excellently for nearly any application. Whether the duty is radioactive food and water monitoring, contaminated soil and water detection, or isotope identification, the Berkeley Nucleonics PalmRAD 907 can provide the robust functionality, yet simplicity, you need to provide accurate and reliable radiological data each and every time.

There is a digital display of the selected mode and three other types of indicators - a LED indicator, an audio alarm, and an audio chirp. The LED flashes with each count. The palmRAD 907 has a user adjustable alarm threshold. When the selected level has been exceeded the powerful audio alarm will sound. The audio chirp, when enabled, emits a single chirp with each count detected. With Berkeley Nucleonics, you can have low cost, reliable, and proven nuclear radiation contamination detection in the palm of your hand.
