This listing is for one Thermo Scientific RadEye PRD4 Personal Radiation Detector with current independent third party calibration.
This is the RadEye PRD4, a late model PRD4 series instrument. It is a compact gamma, X-ray, and neutron capable personal radiation detector designed for high sensitivity source detection, count rate monitoring, dose rate measurement, accumulated dose tracking, neutron indication, and cosmic ray monitoring functions.
This unit is currently configured in R based units, but it can be switched to Sv based units upon request before shipment.
Calibration
This instrument was professionally calibrated by an independent third party radiation measuring instrument calibration provider.
The calibration provider specializes in radiation detection and measuring equipment calibration and is licensed by the state for this type of work.
Calibration was performed using standards with current NIST traceability. The calibration certificate is included with the instrument and reflects the current calibration status of this exact unit.
The calibration documentation includes the instrument information, serial number, calibration date, calibration results, and supporting traceability information.
User Configuration Access
The accessible user configuration menus have been checked and are available for normal user setup.
Available settings include display units, alarm thresholds, response behavior, operating modes, and other user accessible options supported by the instrument.
Please ask if you are looking for a specific function and we will be happy to send additional pictures.
