These measurements are used to determine the human exposure to pollutants and can be combined with trace/background monitoring as well as stack monitoring to assess an organizations contribution to pollutants, and the effect this has compared to natural levels. We provide anayser shelter constructed from various material such as stainless steel SS304 or SS316 or painted galvenized steel. The shelters are designed and manufactured to ensure the reliable performance of the analyser and their systems , to ensure an optimum operation and maintenance of the analyser by the plant personnel, to ensure the safety of the personnel, and minimize the impact on the environment at customer plant site. Clean air is made up of nitrogen, oxygen and argon, with traces of other gases such as carbon dioxide. Air pollutants mainly come from the discharges of gases and particles, mostly from industry, motor vehicles and domestic wood burning. There are also natural sources such as windblown dust and smoke from bushfire. Some forms of air pollution create global problems requiring international solutions; for example, upper-atmosphere ozone depletion and acid rain. The enhanced greenhouse effect also falls into this category. The most widespread pollutants include carbon monoxide, volatile organic compounds, ozone, oxides of nitrogen, sulfur dioxide and particles. These substances are used as indicators of air quality. Air pollution can cause health problems. For example, high concentrations of air pollutants (poor air quality) can aggravate existing respiratory diseases such as asthma and bronchitis, or increase the risk of respiratory problems. To protect the environment against harmful and unhealthy levels of air pollution, Environmental Protection Agencies (EPA) adopt objectives to protect a range of beneficial uses, including the health and well being of humans, plants and animals. These policies cover all the major pollutants as well as specific industrial pollutants from chimneys. There are more stringent controls on industrial discharges of pollutants that may have adverse health effects or are highly toxic. We specialise in air quality monitoring instruments and systems. We manufacture our own range of air quality analyser system and are able to offer fully integrated monitoring systems. Our air quality monitoring cover a wide variety of gases from background/trace levels, through ambient systems level. The most common form of air quality monitoring is ambient air monitoring. Ambient air monitoring involves the measurement of “representative” air in urban, industrial and rural areas. These measurements are used to determine the human exposure to pollutants and can be combined with trace/background monitoring as well as stack monitoring to assess an organisation’s contribution to pollution, and the effect this has compared to natural levels. Visibility is also measured as part of an air quality management system for ventilation control, as well as secondary smoke detection.

The SRV Multi Gas Analyser for Nox and Sox gases uses microprocessor control and Direct Extractive detection method to measure high concentration total oxides of Nitrogen (Nox), and total oxides of Sulfuric (Sox). The analyser delivers excellent sensitivity and reliability by using single measurement channel and gas sample accumulator to provide precise measurement of Nox and Sox artifacts. Advanced signal processing provides continuous measurement and NOX, Sox concentrations are corrected for fluctuations in gas temperature/pressure, flow rate and gases converter efficiency. Data can be displayed either in parts per million (ppm) or milligrams per cubic meter (mg/m3). Features : High concentration Nox/Sox measurement using direct extractive detection method. This analyser has been specifically designed for applications with Nox and Sox ranges of 0 - 2000 ppm or 0 - 300 ppm (option) Inbuilt large monochrome LCD display presents real time data, molybdenum converter efficiency, instrument status and historical information in a digital or graphical format. User selectable screens provide access to all instrument setup and diagnostics menus> Stored data can be retrieved via RS232, USB interface or the optional Ethernet connection and uploaded to a TCP/IP network. Ethernet option facilitates data download from an analyzer connected to the internet via a standard web interface. This feature also supports remote access to instrument parameters and the status output screen Auto zero pre-reactor control provides continuous zero function Inbuilt data logger uses Flash ROM with storage capacity up to 150 days of 5 minute data. It has facility to calibration functions like Auto Zero and Auto Span settings. Pre- Settable Sampling and Purging, data logging times Memory clear facility. Real time clock (RTC) facility. Ranges display : Auto-ranging 0-2000 ppm, (2), optional 0-300 ppm Resolution equals : 0.01ppm Analogue out : 4-20mA Temperature Range : 10ºC to 60ºC. Relative Humidity : 0% to 80% non-condensing.

LISA - SAC254 - the new low-cost state-of-the-art SAC 254 nm instrument from TriOS optical sensors. Innovative long lifetime UV-LED technology and a robust design are the key-features of LISA. Like every TriOS sensor, LISA has nano coated windows to avoid fouling. Combined with airblast cleaning service costs are reduced to a minimum. The unique TriOS G2 interface allows easy and fast 3rd party integration to existing SCADA systems or dataloggers, beside the use within the wide range of TriOS controllers and handheld devices. Additional to the digital outputs, LISA is available with direct 4..20 mA interface. LISA can be customized with optical path lengths of 1, 2, 5, 10 or 50 mm to cover almost every application. The use of a second wavelength offers automatical internal turbidity correction of the SAC value. The titanium version of LISA allows the use in very harnished environments (e.g. high chlorine concentrations). Application depending correlations to COD, BOD or TOC can be done, offering online measurement of this parameters at a fraction of investment and service costs of other SAC254 probes or classical cabinet analysers.   Technical data Input data Parameter SAC254, CODeq, BODeq, TOCeq Measurement accuracy 0.2 % Turbidity compensation at 530 nm Data logger ~ 2 MB T100 response time 4 s Function and system design Measurement principle Attenuation, transmission Light source 2 LED (254 nm, 530 nm) Detector Photo diode + filter Optical path 1 mm, 2 mm, 5 mm, 10 mm, 50 mm Auxiliary power Interface digital Ethernet (TCP/IP), RS-232 or RS-485 (Modbus RTU, TriOS) Interface analog Ethernet (TCP/IP), 4...20 mA Power supply 12-24 VDC (± 10 %) Output data Power consumption Environmental conditions Sample temperature +2...+40 °C Ambient temperature +2...+40 °C Inflow velocity 0.1-10 m/s Performance characteristics Maintenance effort Guarantee 1 year (EU: 2 years) Installation Max. pressure with SubConn 30 bar Max. pressure with fixed cable 3 bar Max. pressure in flow cell 1 bar, 2-4 L/min Protection type IP68 Structural design Housing material Stainless steel (1.4571/1.4404) or titanium (3.7035) Weight stainless steel ~ 1.6 kg (with 10 mm path) Versions item number article 14SXXXXX0 LISA-254 LISA-254 1 4 S X X X X X 0 Path length 0.3 mm 0 1 mm 1 2 mm 2 5 mm 3 10 mm 4 50 mm 5 100 mm 6 150 mm 7 250 mm 8 Sensor Flange None 0 DN50 1 DN80 for cleaning bond 2 Material Stainless steel Titanium Interface Digital: MODBUS RTU RS232 / RS485 0 Analogue: 4 … 20 mA 1 Connector 10 m fixed cable with M12 plug 0 SUBCONN 8pin micro 1
