The PM1703M/MA perform the following functions: 

               Detect gamma radiation sources, even if they are shielded; 

               Alert the user of the presence of a radiation source through audible, visual and vibrating alarms;

               Record and store data for up to 1000 events in the instruments' non-volatile memory; 

               Transmit all recorded data to a PC via IR channel for the data processing and analysis.

Once the detector is turned on, it automatically starts taking measurements and storing the background radiation information. The personal radiation detectors PM1703M and PM1703MA can detect even the slightest increase in radiation environment that causes the radiation levels to exceed the preset thresholds. The instruments' advanced processing algorithm enables the user to update the background levels and setup the alarm thresholds thus adjusting to the specific radiation environments and satisfy the requirements for the false alarm rate.

 

The PM1703M/MA are additionally designed to ensure adequate adaptation to the background level so that the instruments can locate a radioactive source in changing environments. For example, the detectors are able to detect radiation sources when the background decreases due to radiation shielding or when the background radiation intensity is high requiring the source to be located among high radiation level.

 

The PM1703M/MA have a hermetic and shockproof case and the LCD screen's fluorescent backlight for easy operation even in the harshest, most unfavorable environments or weather conditions. The personal radiation detectors are recommended for first responders, security guards, police, customs officers and border patrol. No special experience or training is necessary to operate the instrument.
