  1. 1. Enviro Technology Services plc Air Quality Monitoring ET digital Air Quality Systems and Networks are the most advanced and flexible systems available. Utilising Integrated Digital Technology (IDT), data retrieval is redefined and the standard for air quality monitoring systems reset. Open-path AQM System Designed with the user in mind, ET’s systems are compact, simple to operate, easy to maintain and are guaranteed "future-proof". A wide range of continuous gas, particulate and meteorological sensors is available and both analysers and sensors can be used together as an integrated system or as stand-alone units. Adding a new analyser is simple – just plug in to the digital RS232 switch and make a quick change in the EnviMan software. • Internationally approved analysers - US EPA, MCERTS, TÜV, TA Luft, CE, CEN • Gas analysers available for SO , NO, NO , NO , CO, O , VOCs, Benzene, 1,3 Butadiene, 2 2 X 3 H2S, N2O, NH3 and others • Dust analysers and samplers for PM10, PM2.5, TSP, heavy metals, nitrates/sulphates. • Meteorological sensors for wind speed, wind direction, temperature, relative humidity, MCERTS Approved Gas Analysers pressure, precipitation, solar radiation, etc • Analyser integration using Integrated Digital Technology (IDT) – NEW internal datalogging, digital data transfer and remote system operation Data collection • Flexible calibration options using traceable and certified calibration sources capability • Communication using modem, GSM, GPRS, satellite and ethernet/broadband. via internet/ broadband
  2. 2. Air Quality Monitoring Open-path Monitoring Point Source Monitoring Enviro Technology specialises in Enviro Technology has been a leader in the design open-path, air quality monitoring and manufacture of air quality monitoring systems systems based on Differential Optical since it was formed in 1983 and its analysers are to Absorption Spectroscopy (DOAS). be found throughout the world in thousands of DOAS systems are fully automatic, monitoring applications. Open-path extremely flexible and, due to a The latest generation of analysers bring improved Monitoring System minimum of human intervention, cost-effective to performance, less drift and less temperature run. Every minute, several thousand cubic metres coefficient as a result of the use of advanced of air interact with a beam of light between a electronic, surface-mounted components and light-source and a receiver to provide a more improved control algorithms. The number of representative sample than can obtained with printed circuit boards has been halved and all cards point sampling techniques. are interchangeable between machines leading to One ET system will operate several light-paths easier and quicker card replacement. An extensive continuously measuring multiple gases over paths of internal Data Acquisition System, utilising the up to 1 km long. Any gas specified in the system’s analysers’ internal records, is capable of logging software can be measured, providing a facility to multiple parameters to a total of 1 million records. meet specific needs in a wide variety of applications. ET gas analysers are MCERTS and US EPA ET systems are MCERTS, TÜV and US EPA approved. approved. 100 UV Fluorescent Series Combines the proven UV fluorescent principle ET System 300 Multi-gas System with state-of-the-art microprocessor technology to This high performance package is designed for provide accurate and dependable measurements of urban, trend, fence-line, street canyon and model SO2, H2S, TRS, and sulphur compounds. validation applications. The system is available in three configurations – Basic (SO2, NO2 and O3), 200 Chemiluminescent Series BTX (benzene, toluene and xylene) and Basic/BTX Provides the sensitivity, stability and ease of use (combining all compounds). needed for ambient or continuous dilution monitoring of NO-NO2-NOX, NH3 and O3. 300 IR Absorption Series Measures low ranges of CO, CO2 and N2O by comparing infrared energy absorbed by a sample to that absorbed by a reference gas according to Beer-Lambert law. 400 UV Absorption Series Microprocessor-based with simple, multi-tasking, menu-driven software, for single pass, single path measurements of O3. 700 Mass Flow Calibrator Series Combines highly accurate mass flow controllers and compressed sources of standard gases to provide calibration gases for multi-point span and zero checks.
