Survey meter PM1405 Polimaster

Features

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.

A modification with option of measurement of the ambient dose equivalent ( DE ) of gamma and X-ray radiation and measurement of the α-particles flux density ( surface contamination level measuring ) is available by individual order.

Benefits

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;

Indication of the battery discharge level;

Simple and intuitive user interface.

The PM1405 user software enables

Reading out events information from the instrument’s non-volatile memory;

Conducting on-line real time measurement and displaying the results in digital mode;

Read/record operation settings of the connected instrument:

- DE and DER threshold values;

- History saving/recording interval;

- Measurement units;

- Enable/disable different alarm types.

Save measurement history on PC ( history export );

Early warning about probability of radiation contamination.

Application

PM1405 applications include, but are not limited to use in the following areas:

For personnel safety while working with ionizing radiation sources;

First responders;

Security and customs services;

For wide range of specialists 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.)

Civil defense;

Emergency services.
