Canberra ADM-300 Multi-Purpose Survey Meter

The Canberra ADM-300 is a versatile, portable, multi-functional radiation survey meter designed for detecting and measuring alpha, beta, gamma, and X-ray radiation. Its robust construction and intuitive interface make it suitable for a wide range of environmental, industrial, and scientific applications in the USA. The instrument utilizes advanced “Time-to-Count” Geiger-Mueller detector technology to ensure high accuracy and linearity across a broad dynamic range, mitigating issues like dead time and saturation common in conventional detectors. The ADM-300 features both analog and digital displays for comprehensive data presentation, including dose rates and accumulated dose, with alarms independently settable for both parameters. When used with optional external “smart” probes, the ADM-300 can expand its detection capabilities to include alpha, beta, gamma, and X-ray radiation, with these probes storing their own ID and calibration data.
