The TunnelTech 200 series are primarily gas monitors with optional Visibility capability. Most use Infra-red absorption technology to monitor gaseous pollutants and those with a visibility channel use optical attenuation for that application. All TunnelTech 200 analysers except the TunnelTech 205 use the same rugged corrosion resistant enclosures and have an optional Data Display unit. As there is only one moving part so reliability levels are very high and maintenance levels very low.
Focuses on low NOx and NOx-related concentrations up to 100 ppm where high resolution is required. Parameters included are NO, NO2, NOx and NOy. Target applications are ambient air monitoring, indoor measurement, clean room measurement and atmospheric research.
The new and unique AS32M NO2 analyzer using CAPS (Cavity Attenuated Phase Shift) technology is an ideal solution for medical device applications such as INO (Inhaled Nitric Oxide). Originally designed for NO2 monitoring in roadside pollution surveillance and air quality applications, the AS32M is suitable for numerous other NO2 monitoring applications.

Focuses on medium NOx, NOx-related and multigas-concentrations up to 5’000 ppm where flexibility is a central requirement. Parameters included are NO, NO2, NOx, NH3, NOx-amines, O2 and CO2. Typical supported applications are industrial emission monitoring and gas manufacturing control.
In some countries they do not allow tunnel atmosphere monitors to be mounted on the tunnel wall; also, where there is a single bore it is very difficult to gain access for maintenance purposes. The TunnelTech 400 series are extractive gaseous pollutant and visibility monitors and extract a gas and dust sample from the tunnel bore and carry to a remote analyser. This allows maintenance to take place without affecting tunnel traffic flow.
Focuses on high NOx, NOx-related and multigas-concentrations up to 10’000 ppm. Parameters included are NO, NO2, NOx, NH3, NOx-amines, O2 and CO2. The applications are characterized by demanding sample gas conditions, such as in automotive, aviation, naval, or combustive engine emissions, as well as in catalyst production.
In most combustion process atmospheric nitrogen reacts with oxygen in high temperature conditions to produce nitrogen oxides (NOx). Total NOx production is the sum of nitrogen monoxide NO and nitrogen dioxide NO2. The emissions of these gases are controlled through setting of emission limit values (ELVs) for power plants.
Opsis provides state-of-the-art monitoring equipment, fully meeting the high standards of monitoring performance and reliability that the cement industry requires. The Opsis in situ systems are designed to withstand environments with high particulate levels and high temperatures.
Process control of a SO2 scrubber on a ship is a challenge due to wet and corrosive gases. In such environment, extractive gas sampling systems require high levels of maintenance in order to operate correctly. OPSIS monitoring system solves this by using an optical, non-contact, cross-duct technique. A light beam is sent across the duct or stack to be measured, and the captured light is sent through an optical fibre cable to an analyser. The analyser measures SO2, CO2 and NOx concentrations using UV and IR...
NOy (total reactive nitrogen) is defined as the sum of NOX plus the compounds produced from the oxidation of NOx which include nitric acid. NOy component species include NO, NO2, NO3, HNO3, N2O5, CH3COO2NO2(PAN), and particulate nitrate.
NOx detection is an innovative approach in CMP (Chemical Mechanical Polishing) process control. CMP smoothens the wafer surface with a combined chemical and mechanical polishing procedure. During production, wafers are coated by a thin layer. To avoid damage to the wafer surface, for instance by stress cracks, the NOx emitted as soon as the wafer is plane and blank must be measured. Therefore, a high-resolution NOx-detector, capable of determining exactly when the polishing process must be stopped, is essential....
Oxides of Nitrogen (NO/NO2/NOX) is the product of endothermic reactions within combustion engines and causes significant environmental pollution. The main source of NOX is from the engine of automobiles and these pollutants are harmful to humans in their respective forms or in the creation of ozone (O3) or acid rain. NOX is most prevalent in our societies as a contributor to asthmatic conditions as well as the photochemical smog found throughout many industrialized cities.
