Alpha 7A Alpha Aerosol Monitor

A mix of reliability and high level of performances


The Alpha-7A is a Continuous Air Monitor (CAM) designed to provide early warning to workers exposed to airborne releases of alpha-emitting radionuclides.


  • Adjustable alarms
  • Advanced peakshape algorithms
  • Removable filter holder cartridge
  • High visibility display for status and messages

Modern, PC-based continuous air monitor provides faster, more powerful algorithms for the identification and quantification of airborne releases of alpha-emitting radionuclides, primarily transuranics such as 238Pu and 239Pu.

The ALPHA 7A has adjustable alarms, at both DAC and DAC-hour levels, to quickly warn workers of potentially dangerous releases. As well as monitoring work areas the ALPHA 7A is also a brilliant solution for monitoring stacks and ducts.

Two detector designs:

Radial entry head for ambient air monitoring

Inline head for process or stack monitoring applications

Compatible with Thermo Scientific RAP-1 pump
