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.

Use the Black Carbon Module to indicate this extremely harmful component of particulate matter, with impacts ranging from human health to reduced agricultural productivity, and even global warming.

The Black Carbon Module is a real-time 5-wavelength UV-IR Black Carbon monitor.

Designed to be installed outdoors on street poles and along fence lines, it also features an accelerometer, altimeter/barometer, and sensors for relative humidity and temperature. The spectrum measurement provides insight into the composition of light absorbing carbonaceous particles and helps to distinguish among the different optical signatures of various combustion sources such as diesel, woodsmoke, biomass and tobacco.

LaserHawk Model 360 Brochure

LaserHawk Optical Head

The Optical Head is housed in rugged NEMA 4 aluminum castings.  The Optical Head contains the active electronics necessary to project a laser beam across the stack/duct to the Retroreflector assembly and to detect reflected light.  The sealed Optical Head subassembly is designed for simple cover removal, allowing complete access to the electronics.

Purge System

A purge air system is furnished with each LaserHawk^®.  The system supplies purge air to the Optical Head, protecting the instruments from stack gases and significantly reducing maintenance intervals.  A Purge Air sensing switch is provided in case of power loss or interruption.  Purge fail/power fail alarms are standard.

Optical Head Keyboard/Display

Uses a 10 button keypad & 6 digit readout to display and/or enter:

• Instantaneous Particulate Concentration (mg/m³ or gr/ft³)
• Average Particulate Concentration
• Upscale Calibration
• Zero Calibration
• Dust Compensation
• Status Codes
• Diagnostic Data about the Analog Signals Inside the Optical Head (no need to open the Optical Head)
• Particulate Concentration Curves
• Optical Gains
• Alarm Settings.

With optional Six Point I/O board, LaserHawk^® meets all PS-11 requirements without a Remote Display Panel.

Enhanced Remote Panel

Uses a large, back-lit, LCD graphics display with English-language, menu driven screens, providing ready access to all information needed for full use of the system. In addition, the user can graph up to the most recent 100 values of a selected parameter, such as:

• Instantaneous dust concentration, average dust concentration
• Calibration Values (Zero, Upscale, or Dust Compensation)

The keypad, a rugged 20-button ensemble inlaid under a tough, hard coated, scratch and chemical-resistant Lexan coating, can be used to:

• Display Dust Concentration in mg/m³ or gr/ft³ basis
• Identify the Cause of an Alarm or Malfunction
• Configure the Relay Outputs
• Configure the Analog Outputs
• Edit Parameters such as Voltages, Currents, and Gains
• Set Alarm Values for Dust Concentration, Zero Cal and Upscale Cal
• Load Correlation Curves for Particulate Concentration.

Calibration Kit

The calibration kit, standard with the LaserHawk^®, is used as an additional check of the unit’s proper operation and calibration. The calibration fixture attaches to the front face of the optical head and has been preset to return the same amount of light as the retroreflector when the stack or duct is clear.

Ethernet Interface

The LaserHawk^® Enhanced Remote Panel now features 10/100 Based Ethernet interface as standard equipment. This capability provides a multilevel password protected interface to TCP/IP networks such as LAN’s or the Internet. Client side user interface access is via standard web browsers. Simultaneous Modbus TCP access to instrument parameters and emission data is also supported.

Lighthawk Model 560 Brochure

The heart of the Opacity/Dust Monitor is an electronically modulated (2400Hz), intensity controlled LED located in the Optical Head assembly. Light from the LED is projected from the Optical Head across the stack/duct sample area to a Retroreflector on the opposite side. The reflected light re-enters the Optical Head, where it is evaluated by a signal detector. If the stack is clear, the light transmission is 100% (zero opacity). When the reflector returns no light, the transmission is zero (100% opacity). Opacity can be correlated against a reference methods to calculate dust loading.

LightHawk Optical Head and Retroreflector Assemblies

The Optical Head and Retroreflector Assemblies are housed in rugged aluminum castings. The Optical Head contains the active electronics necessary to project a light beam across the stack/duct to the Retroreflector assembly and to detect reflected light. The sealed Optical Head subassembly is designed for simple cover removal, allowing complete access to the electronics.

Purge System

A purge air system is furnished with each LightHawk®. The system supplies purge air to the Optical Head and the Retro-reflector, protecting the instruments from stack gases and significantly reducing maintenance intervals. Purge Air sensing switches and optional aluminum fail-safe shutters are provided in case of power loss or interruption. Purge fail/power fail alarms are standard.

Enhanced Remote Panel

Uses a large, back-lit, LCD graphics display with English-language, menu driven screens, providing ready access to all information needed for full use of the system. In addition, the user can graph up to the most recent 100 values of a selected parameter, such as:

• Opacity, Optical Density, or Particulate Concentration (averaged or instantaneous)
• Calibration Values (Zero, Upscale, or Dust [compensation])

The keypad, a rugged 20-button ensemble inlaid under a tough, hard coated, scratch and chemical-resistant Lexan coating, can be used to:

• Display Opacity, Optical Density, or Particulate Concentration
• Configure the Relay Outputs
• Configure the Analog Outputs
• Edit Parameters such as Path Length Correction Factor
• Set Alarm Values for Opacity, Cal Zero, and Upscale Cal
• Load Linearization Curves for Correlation to Particulate Concentration

Standard with the LightHawk® Remote Panel is a security keylock for protection of important calibration parameters. System elements communicate over a single twisted pair using a commercial network communication protocol. Bright LED indicator lights are used to indicate faults and alarms. The four optically-isolated analog outputs, normally packaged within the Remote Panel can also be offered in a separate housing for convenient installation.
