BAM 1020

Continuous Particulate Monitor (Model BAM-1020)

The BAM 1020 provides unsurpassed accuracy, reliability and simplicity.

The BAM-1020 automatically measures and records airborne particulate concentration levels (in milligrams or micrograms per cubic meter) using the industry-proven principle of beta ray attenuation. Thousands of BAM-1020 units are currently deployed worldwide, making the unit one of the most successful air monitoring platforms in the world.

  • Excellent value for money. The BAM-1020 is extremely cost-effective, to buy, operate and run. The sample tape lasts for 60 days providing hourly mass measurements so local site operation in only required once every 2 months.
  • Compact, rugged and reliable. The BAM-1020 has been in production for over 15 years and has earned an excellent reputation internationally for it's reliability, accuracy and ease of use.
  • EU/UK Approved equivalent method for use on all UK monitoring networks. The BAM-1020 was one of only a select few instruments tested to comply with the CEN 1234-1 reference method during the 2005 BV inter-comparison.
