Detail

 Polimaster model РМ1405 is a compact multifunction survey meter, capable of measuring X-ray, gamma and beta radiation. It is designed for the wide range of radiation safety applications and may be successfully used by radiation control services personnel, first responders, employees of security service and customs, as well as personnel whose work includes solving problems of local gamma and beta radiation sources detection or single objects contaminated by gamma and/or beta radiation sources (for example, to determine radioactive contamination of banknotes, scrap, etc.).

The РМ1405 survey meter incorporates a large energy compensated GM tube for precise measurement of the ambient equivalent dose rate of the X-ray and gamma radiation in the range from background level to 100 mSv/h (10 R/h). By opening the special screen-filter and choosing beta radiation flux density measurement mode, the instrument allows to estimating the intensity of the contamination of surfaces of various environmental objects from beta radiation sources.
Being compact in size and light weighted the survey meters may be used for search, detection and localization of gamma and beta radiation sources. The search process is accompanied by sound and light signals with the intensity of the signal proportional to the radiation rate. 
 
Product features:
Simultaneous and selective measurement of the gamma and beta radiation intensity;
Audible and visual alarms at the levels, exceeding user preset threshold values and in the radiation source search mode;
Non-volatile memory;
PC communication via USB interface and the ability for networking instrument with automatic data collection into a server based centralized database;
Indication of the battery discharge level;
Simple and intuitive user interface.
 
The unique PM1405 user software allows to connect and network in information system up to three hundred instruments, as well as to carry out direct (software local mode) or remote (software remote mode) control, monitoring and information collection from all connected РМ1405. The user software performs continuous radiation control with transfer of the information from the instrument to a client PC (local mode) and server PC (remote mode).
 
The PM1405 user software enables:
Higher work efficiency of radiation control services personnel, first responders, employees of security service and customs, as well as personnel whose work includes solving problems of local gamma and beta radiation sources detection or single objects contaminated by gamma and/or beta radiation sources (for example, to determine radioactive contamination of banknotes, scrap, etc.).
Transfer of information about radiation situation on the controlled area or object in online mode;
Creation of automatic reports about control efficiency during the detection of radioactive contamination by beta and gamma sources;
Early warning about probability of radiation contamination.
