The Clarity Multi-Gas Module expands the capabilities of the Node-S, enabling real-time measurement of CO, O₃, NO₂, NO, and NOx — five key pollutants that impact air quality and public health. Whether monitoring urban pollution, industrial emissions, or transportation corridors, this compact, all-in-one sensor provides high-quality data without the complexity of multiple instruments.

Designed for effortless deployment, the Multi-Gas Module features a weatherproof, UV-resistant enclosure and modular mounting for quick installation on both vertical and horizontal poles. With Clarity’s plug-and-play Add-On Module design, the Multi-Gas Module leverages the solar-powered operation and built-in cellular connectivity of the Node-S — even when paired with the Wind Module.

Multi-Gas Module use cases

CO and wildfires

CO is a by-product of combustion, emitted by both wildfires and urban sources
Wildfires produce significantly more PM2.5 per unit of CO than urban sources
The PM2.5-to-CO ratio helps distinguish wildfire smoke from urban pollution.

NOₓ and traffic

High NO and NO₂ levels identify traffic-related pollution hotspots
A higher NO-to-NO₂ ratio indicates fresh emissions near the source, while a lower ratio suggests chemical transformation as the air moves further away.

O₃ non-attainment and smog formation

Quantify diurnal pattern of NOx (morning, evening peaks) and O3 (afternoon peak)
Elevated NOₓ and O₃ together signal strong photochemical activity and smog formation.

TELEDYNE API Model N500 CAPS NOx (TAPI)

thomson-admin — Fri, 05 Jul 2019 02:18:47 +0000

The Teledyne API Model N500 CAPS NOx analyser is a Cavity Attenuated Phase Shift (CAPS), non-chemiluminescent NOx analyser.

Using CAPS Spectroscopy to measure ‘true’ NO2, NOx and NO gases, the Teledyne API Model N500 provides an improved option for NO2, NOx and NO measurement accuracy and reduces instrument operation and maintenance costs.

CAPS technology is inherently accurate and sensitive, requires less maintenance than chemiluminescence and uses less power.

Teledyne-API’s first direct true NO2 analyser, the T500U has been a popular instrument with scientists and air quality specialists looking for a faster and more precise measurement of NO2 that cannot be offered by chemiluminescence.

The Model N500 like the T500U, uses CAPS technology for true NO2 measurement but it adds the ability to measure the NO component of NOx. The instrument combines direct NO2 measurements with highly efficient gas phase titration (GPT) to convert and measure the NO gas component.

The new Model N500 CAPS NOx / NO2 / NO analyser is available exclusively in Australia and New Zealand through Thomson Environmental Systems.

NOVA Continuous Gas Analyzers

thomson-admin — Wed, 26 Sep 2018 05:10:13 +0000

Continuous gas analyzers comprise a significant portion of the Nova Analytical product line. These types of instruments are generally used for continuous gas analysis of an individual sample point in a facility.

Because these analyzers are intended for permanent exposure to the sample gas, they must be equipped with suitable sample conditioning components. This means that continuous analyzers are bigger than portable analyzers, and they are almost always permanently mounted to a wall or other vertical surface.

Gases analysed: O2, CO, CO2, , CH4, H2, NO, NO2, NOx, SO2, Dew Point, LEL Combustibles, NH3, Hydrocarbons, He, Temperature, Velocity, SF6, HCI, CI2, Multi-Gas Combinations

NOVA Portable Gas Analyser

thomson-admin — Wed, 26 Sep 2018 05:04:29 +0000

Nova Analytical Systems’ series of portable gas analyzers provide accurate, real-time sample gas data in industrial environments, lab settings, and others. They are more compact than wall-mount gas analyzers, yet provide reliable spot-check measurements when and where they are needed.

The small size of portable analyzers limits the available internal space for sample conditioning components. This means that they are not equipped to do long-term analysis of challenging sample gases. However, they are ideal for spot-check and tuning applications.

TELEDYNE API T200 / T200U NO/NO2/Nox Series (TAPI)

thomson-admin — Tue, 25 Sep 2018 12:03:38 +0000

The Model T200 NO/NO2/NOx analyzer uses the proven chemiluminescence detection principle, coupled with state-of-the-art electronics to allow accurate and dependable low level measurements for use as an ambient analyzer or dilution CEMS monitor.

A unique AutoZero feature provides superb stability by continuously correcting for zero drift, while advanced Adaptive Filtering allows the analyzer to optimize performance under changing conditions. The Model T200 includes a permeation inlet dryer for ozone generation to provide excellent reliability with no periodic replacement required. A catalytic exhaust ozone scrubber is standard for maximum safety and pump life.

The Model T200U Trace-level NO/NO2/NOx analyzer has been developed specifically to address the challenges of low level monitoring as required, for example, in the US NCore network. It uses the proven chemiluminescence principle and is designed to allow ultra-sensitive measurements with a lower detectable limit of 50 ppt while still meeting the requirements for use as a US EPA compliance analyzer.

The Model T200U combines a gold plated reaction cell with an enhanced performance pump, special low noise photomultiplier tube, and unique signal conditioning to provide exceptional sensitivity. In addition, a pre-reactor separates the NO-O3 reaction from background chemiluminescence to allow accurate auto-zero of the analyzer.

All T Series instruments offer an advanced color display, capacitive touch screen, intuitive user interface, flexible I/O, and built-in data acquisition capability. All instrument set up, control and access to stored data and diagnostic information is available through the front panel, or via RS232, Ethernet, or USB com ports, either locally or by remote connection.

The Model T200 comes with NumaView Software. NumaView Remote PC Software allows for a remote connection with virtual interface and data downloading capability to analyzers operating NumaView Software.
