Unitec ETL-One多参数空气质量监测仪产品页英文

The ETL One is the new All-In-One 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 multiparametric 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 IP55 case permits easy and direct outdoor installation (no cooling system or air treatment are required!). The Unitec SENS-IT gas sensors are based on proprietary technology and can monitor continuously gas pollutants in outdoor applications ensuring excellent sensitivity and selectivity (also at ppb levels), with no needs of frequent maintenance or calibration. Each SENS-IT sensor is specific for a single gas and independently connected to the datalogger with plug-in connector, for easy infield replacement. 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 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, ecc. Different software solutions are also available for data download, data export, unit configuration, geolocalization, real-time visualization, ecc.
