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.

Ideal for monitoring air quality outside or in workshops, TES Small Form AQMS measures key parameters:

Air pollutant concentrations: PM₁, PM_2.5, PM₄, PM₁₀, TSP, O₃, NO, NO₂, O3, CO, SO₂, H₂S, NH₃, HCHO, Cl₂, HCl, VOC, CH₄, CO₂ – other gases available on request

Meteorological parameters: temperature, pressure and relative humidity

Other parameters: noise, vibration and odour

Location: GPS

The device captures data in real-time and transfers them wirelessly to a advanced web platform, for data analysis and data management, remote control of the equipment and data integration into websites, software and smart city platforms.

Small form stations are light, compact and easy to install within just a few minutes. Once the stations are connected to the Internet through several communication links on-demand (Wi-Fi, 3/4G, LoRa, Zigbee…), the hyper-localised information is automatically transferred to a secure web platform that is accessible 24 hours a day.

Customize your own Small Form AQMS that meets your needs:

Options:

• Integrate sensors that you need
• Choose your communication link
• Add a back-up battery 

Accessories:

• Solar panel and batteries
• Heating resistance
• Mounting plate

For a wide range of applications:

Smart cities, industrial sites, mining sites, sewage treatment plants, mines, soil remediation, refineries, workshops, warehouses, worksites, road networks, race tracks, ski, and sea resorts.

The 751H includes a dew point sensor, a small, powerful pump, scrubbers to remove SO2, NO, NO2, O3, H2S, and NH3 plus high performance scrubbers to remove CO and Hydrocarbons. The regenerative heatless dryer removes water and produces output with a dew point of -20ºC (up to 10 SLPM flow rate).

The 751H features tank-less operation for real-time pressurised output without “pulsing.” A micro-controller cycles the regenerative dryer and pressurized drain and features a short cycle interval of 1 minute for high humidity applications.

Features

• Rugged traveling case with wheels and retractable handle
• Dew point indicator
• Long life scrubbers for SO₂, NO, NO₂, O₃, H₂S, and NH₃
• High Performance CO/Hydrocarbon scrubber
• Regenerative, heat-less dryer for maintenance-free water removal
• Automatic water drain
• Once/year maintenance interval
• Two-year warranty.

Model 430 carries US EPA Federal Equivalent Method EQOA-1015-229 certification.

The Model 430 Compact O₃ Analyzer uses the proven UV Absorption principle, to produce accurate and stable O₃ measurements. The robust design and low power consumption makes it ideal for portable monitoring applications such as rural and remote monitoring, saturation studies, and atmospheric research.

The small footprint and quiet operation make it extremely useful for indoor air quality, surveying, and industrial hygiene applications. An optional battery pack provides up to 14 hrs of run time on a full charge.

Model 430 Features

• Well-suited for portable, low power monitoring applications.
• 2.4 Kg weight and 10 x 18 x 26cm in size
• Proven UV Absorption method used in Teledyne API’s range of popular Industrial Ozone products
• High quality construction
• Rugged and lightweight ABS polycarbonate chassis with handle
• Wide operating range 0 – 100 ppb to 0 – 20,000 ppb (user-selectable) and Lower Detectable Limit < 2 ppb
• US EPA Federal Equivalent Method EQOA-1015-229 certification.

A 254 nm UV light signal is passed through the sample cell where it is absorbed in proportion to the amount of ozone present. Periodically, a switching valve alternates measurement between the sample stream and a sample that has been scrubbed of ozone. The result is a true, stable ozone measurement.

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 T400 comes with NumaView Software. NumaView Remote PC Software allows for a remote connection with virtual interface and data downloading capability to analysers operating NumaView Software.

Features

• Ranges: 0-100 ppb to 0-10 ppm, user selectable
• Single pass ultraviolet absorption
• Selectable ranges, with dual range capability
• Large, vivid, and durable color graphics display with touch screen interface
• Ethernet, RS-232, and (optional) USB com ports
