AT1121 X-ray and Gamma Radiation Survey Meter
Measurement of continuous and short-term X-ray and gamma radiation ambient dose equivalent and ambient dose equivalent rate. Search and detection of X-ray and gamma radiation sources, and high-level beta radiation sources with maximum spectrum energy of more than 500 keV.
- Measurement over a wide range of dose rates and energies
- Measurement of dose rate and exposure time during short-term exposure (from 0.03 s)
- Automatic recording of over 500,000 measurement results into non-volatile memory
- One of four available averaging modes can be selected
- Remote control is optionally available for distant measurements
- Optional stationary placement with external audio-visual alarm and potential-free contacts for actuator control
- PC communication interface for a continuous monitoring and data logging
