Survey Meter Polimaster PM1405
Not available
Delivery time: 1-2 day(s)Description
- Professional Digital Radioactivity Detector, compact and designed for general purpose. Detects alpha, beta, gamma and x-rays.
- Used for a wide range of radiation monitoring applications, including measurement of ambient gamma radiation, X-ray leak detection, search and measurement of radioactive contamination, and specific measurement of surface contamination by beta emitters.
- The monitor has a movable screen, to enable discrimination between gamma, and beta/alpha radiation; with the screen inplace, the monitor acts as a compensated Geiger monitor for gamma radiation dose measurement, while uncovering the screen allows the monitor to measure lower energy X-ray and gamma radiation, and alpha/beta radiation.
- The instrument activates an alarm if radiation levels exceed a pre-set threshold. The PM1405 is supplied with software and USB and cable to enable real-time visualization of radiation level on a PC, change instrument configuration, and retrieve data stored in the instrument's memory.
