The World's First Dual-Sensing Industrial Camera: Why Industry Giants Are Choosing the HA3LX Over Traditional OGI

In the high-stakes world of industrial safety and fugitive emission monitoring, visibility is not enough—you need quantification.

HERTZINNO is proud to announce that our flagship innovation, the HA3LX, is rapidly becoming the new standard for methane leak detection. As the world's first handheld camera to integrate 144-channel acoustic imaging with TDLAS laser methane detection, the HA3LX offers a capability that traditional Optical Gas Imaging (OGI) cameras simply cannot match: Simultaneous Positioning and Quantification.

This groundbreaking technology is already deployed in the field by global energy leaders, including Shell Canada, PetroChina (CNPC), Sinopec, and CPC Corporation.

HA3LX vs. Optical Gas Imaging (OGI): The "Dual-Sensing" Advantage

For years, Optical Gas Imaging (OGI) has been the go-to solution for visualizing gas leaks. However, OGI technology has significant limitations: it is expensive, qualitative (visual only), and easily affected by environmental conditions.

The HA3LX was designed to overcome these challenges. Here is why the industry is shifting toward our Acoustic + Laser solution:

1. Quantification vs. Visualization

• The OGI Limit: OGI cameras show you a gas cloud, but they cannot tell you how much gas is leaking without complex secondary processing. It provides a qualitative image, leaving operators guessing about the severity.

• The HA3LX Advantage: The HA3LX doesn't just find the leak; it measures it. Using Tunable Diode Laser Absorption Spectroscopy (TDLAS), the device instantly displays the methane concentration in ppm·m. This allows maintenance teams to prioritize repairs based on real data, not just visual estimates.

2. Wind Resistance & Source Pinpointing

• The OGI Limit: In windy conditions, gas clouds drift away from the actual leak source. An OGI operator might see the gas plume but struggle to find the exact valve or flange causing the leak.
• The HA3LX Advantage: Acoustic imaging detects the sound of the leak turbulence, which is generated right at the source. Wind direction does not affect sound propagation in the same way it moves a gas cloud. The HA3LX's 144 MEMS microphones pinpoint the exact leak location, while the laser verifies the methane presence.

3. Specificity & False Alarms

• The OGI Limit: Thermal-based OGI can sometimes be confused by steam, exhaust fumes, or thermal reflections, leading to false positives.
• The HA3LX Advantage: The TDLAS laser sensor is spectrally tuned specifically to Methane ($CH_4$). It ignores steam and other gases, ensuring that every alert is a verified methane leak.

4. Cost-Effective Scalability

• The OGI Limit: High-end cooled OGI cameras are prohibitively expensive ($80k+), limiting deployment to only a few specialized teams.

• The HA3LX Advantage: The HA3LX offers superior quantitative data at a fraction of the cost, allowing companies to equip more frontline operators and increase inspection frequency.

• Technical Breakdown: Built for the Toughest Environments
• The HA3LX is engineered for precision and durability in hazardous zones.
• Unmatched Sensitivity: Features a massive array of 144 Low-noise MEMS Microphones for detecting minute leaks and mechanical faults.
• Extended Range: Detects acoustic signals from up to 200 meters and measures methane concentration with the laser from up to 30 meters (at 3000 ppm·m).
• Rapid Response: The TDLAS module delivers a response time of just 0.25 seconds, enabling fast scanning of pipelines and flanges.
• Explosion Proof: Certified Ex ib IIC T4 Gb (ATEX), ensuring safety in Zone 1 and Zone 2 explosive atmospheres found in refineries and hydrogen plants.
• Intelligent Reporting for Modern LDAR
• Gone are the days of manual note-taking. The HA3LX supports one-click analysis directly on the device. Operators can tag photos with voice notes, text, and data, then instantly export reports via Wi-Fi, Bluetooth, or USB Type-C.
• This seamless data workflow makes the HA3LX the ultimate tool for LDAR (Leak Detection and Repair) compliance and ESG reporting.
