Air Quality Monitoring

The ETL-One is the innovative air quality monitoring solution designed and manufactured by Unitec for indicative measurement(as defined by European Directive 2008/50/EC).

The ETL One is a multipara metric station equipped with Unitec SENS-IT for continuous gas and dust monitoring with high precision and accuracy, featured by easy use and very low ownership costs. The ETL One is equipped with a fully integrated dust monitoring module based on orthogonal light scattering technology for real-time particulate monitoring (PM10 or PM2.5 or PM1). Alternatively the ETL One can be equipped with external OPC dust module for multi PM simultaneous monitoring (PM10, PM2.5 and PM1). For both solution the ETL One has an automatic autozerocalibration system that ensures long-time reliable measurement, reducing drift and maintenance activities. The IP55 case permits easy and direct outdoor installation.

Installation and commissioning in less than 15 minutes, no cooling system or air treatment are required!

Approval certification of Italian CNR (National Council of Research) in reference to European directive 50/2008/EC

Beta Attenuation

  • Measures ambient particulate concentrations using beta ray attenuation
  • Class III FEM, PM10 (EQPM-0798-122) PM2.5 (EQPM-0308-170) PM10-2.5 (EQPM-0709-185)
  • Measurement Of Ambient And Gas Temperatures And Atmospheric And Differential Pressures
  • Range 1 mg (1000 µg) default setting.
  • Settable from 0.1 mg to 10 mg Measurement Cycle Time 1 hour

the BAM 1022 has US-EPA designation for PM2.5 (EQPM-1013-209) for which a dedicated hourly output channel is available. A second, real-time output channel will provide the user with continuous PM updates down to 1-minute time resolution. The BAM 1022 is ideal for the following applications:

  • Criteria-Grade Air Quality Surveillance Networks
  • Near-Roadside PM Monitoring
  • Rapid-Deployment Applications Such As Emergency Responder and Controlled Burn Work
  • Research and Development
