S.E. International MC1K | Handheld Gamma & X-Ray Survey Meter
Rugged, High-Range Radiation Detection for Industrial Safety
The MC1K is a compact, handheld analog survey meter designed specifically for the detection of Gamma and X-ray radiation.Built to withstand the harsh environments of industrial radiography, medical imaging suites, and nuclear facilities, it provides real-time monitoring of dose rates up to 1000 mR/hr.Its simple, four-range interface ensures that operators can quickly and accurately assess radiation levels, ensuring compliance with ALARA (As Low As Reasonably Achievable) safety protocols.
High-Range Detection: Monitors exposure levels from $0$ to $1000$ mR/hr, making it suitable for high-intensity environments like NDT radiography bays and nuclear medicine labs.
Selectable Sensitivity: Features four easy-to-read ranges ($\times 1, \times 10, \times 100, \times 1000$), allowing the user to switch between fine background monitoring and high-intensity source detection.
Energy Compensated GM Tube: Equipped with an internal, energy-compensated Geiger-Mueller (GM) detector. This ensures the meter remains accurate across a broad energy spectrum ($40$ keV to $1.3$ MeV), preventing over- or under-reporting of dose rates.
Audible & Visual Alerts: Includes a built-in speaker that provides a "chirp" relative to the radiation intensity, allowing for eyes-free monitoring, alongside a high-contrast analog needle display.
Ruggedized Construction: Housed in a durable, impact-resistant casing and includes a protective carrying case to safeguard the instrument during field use.

Certificate of Conformance
Safety & Calibration Note: Most regulatory bodies (such as the NRC or equivalent local authorities) require radiation survey meters to be calibrated annually. Ensure your MC1K is sent to a licensed calibration laboratory every $12$ months to verify the accuracy of the analog scales.
