Features:

• Audible and visual alarms
• Telescopic tube and headphones are included
• Data records in non-volatile memory (count rate in preset intervals; alarm events; background re-calibration events; power on/off events)
• LCD display
• PC communication by IR channel
• Easy-to-use

Ratemeter PM1701M is designed to detect and localize radioactive sources by their gamma radiation. The instrument continuously monitors radiation environment and compares to normal background. 

PM1701M is supplied with the telescopic tube and headphones for users` convenience. When the threshold is exceeded, the user will hear an audible signal through the headphones. The rate of audible and light signals increases as the device moves closer to a radiation source.

PM1701M is able to locate radioactive sources in the changing radiation background. The device is able to detect radiation sources in cases of decreased and increased levels of background. (Decreased due to radiation shielding; increased when the source is hidden in the mass of naturally occurring radioactive material (potassium fertilizers or ceramics)).

Application:

• Scrap metal facilities
• Waste disposal and storage sites
• Customs checkpoints
• First responders etc.

Standards comliance:

Designed to meet ITRAP (IAEA) requirements

Applications:

• Uranium Mining and Nuclear Fuel Production
