New Multiparametric Unit for Outdoor Air Quality Monitoring

The ETL One is the new All-In-One air quality monitoring solution designed and manufactured by Unitec (Italy) for indicative measurement (as defined by European Directive 2008/50/EC). The ETL One is a multiparametric station equipped with Unitec SENS-IT for continuous gas and dust monitoring with high precision and accuracy, featuring easy use and very low ownership costs. The ETL ONE is the perfect solution for urban areas, industrial and cement plants, landfills, roadworks and fenceline monitoring. The IP55 case permits easy and direct outdoor installation (no cooling system or air treatment is required!). The Unitec SENS-IT gas sensors are based on proprietary technology and can continuously monitor gas pollutants in outdoor applications ensuring excellent sensitivity and selectivity (also at ppb levels!), with no need for frequent maintenance or calibration. Each SENS-IT sensor is specific to a single gas and is independently connected to the datalogger with plug & play connector, for easy in-field replacement. The ETL One is equipped with a fully integrated dust monitoring module based on optical technology for real-time particulate monitoring (PM10, PM2.5 and PM1). The ETL ONE has an automatic autozero calibration system that ensures long-time reliable measurement, reducing drift and maintenance activities. The built-in datalogger handles all activities, including continuously data acquisition, hourly average storage, dust module automatic daily zero calibration and data transmission. Many options are available: weather stations, GSM modem, UMTS modem (for VPN connection), noise meter, solar panel kit, etc.
