Intrinsically Safe Acoustic Camera with TDLAS Methane Detection
Acoustic imaging and laser-based methane detection are powerful technologies on their own, but some inspections require both. Acoustic imaging can quickly locate a suspected leak from a distance, and laser detection can then confirm the presence of methane and measure its concentration. Combining these two methods in one instrument gives inspectors a practical way to locate a leak first and verify the gas without switching equipment. This is where Pergam’s CRY8125M package comes in.
CRY8125M is an intrinsically safe handheld acoustic imaging camera with a removable TDLAS methane detector module. The camera localizes pressurized gas and vacuum leaks from a distance, while the TDLAS module confirms methane presence and measures its concentration along the laser beam path. The camera estimates the leak rate and associated cost, giving inspectors a quantitative basis for assessing the scale and potential impact of a detected leak.

How CRY8125M Works
CRY8125M uses acoustic imaging to visualise gas leaks and TDLAS technology to detect methane and measure its concentration.
Acoustic Imaging
CRY8125М detects ultrasound produced by gas leaks, partial discharges and mechanical wear. Using a 200-channel microphone array and HyperVision algorithm, it accurately locates the source of the ultrasound while filtering out background noise. The device detects any gas type, measures leak rates, and estimates financial impact to support maintenance planning. It also finds and classifies partial discharges, identifies mechanical issues, and supports an external thermal imaging module for enhanced diagnostics.
Laser Methane Detection
The laser methane detector module of the CRY8125M utilizes TDLAS technology
TDLAS (Tunable Diode Laser Absorption Spectroscopy) technology uses a tunable diode laser for precise gas analysis. The laser emits a narrow beam of light at a specific wavelength that matches the absorption characteristics of the target gas. When this beam passes through the gas and reflects off a surface, part of the light is absorbed by gas molecules. A sensor captures the reflected beam, and the gas concentration is determined by measuring the reduction in light intensity.
Three-Step Inspection Workflow
Three simple steps for a complete leak inspection.
- Step 1
Locate
Scan the asset from a safe distance. The acoustic image marks the leak on the live camera view and estimates the leak rate and cost. - Step 2
Confirm
Point the laser at the same spot. TDLAS measures CH₄ in ppm×m along the beam, distinguishing a methane release from ambient noise. - Step 3
Report
Photos, video and data are transferred via Wi-Fi or USB-C to the reporting software, which generates the inspection report offline.
CRY8125 Applications
CRY8125M is designed for leak inspection in oil and gas, chemical, LNG, power, and utility facilities. Its acoustic imaging camera detects and localises pressurised gas and vacuum leaks from a distance, while the plug-in TDLAS module confirms methane presence and measures its concentration along the laser beam path. The system can be used for inspecting well pads, pipelines, tank farms, compressor and metering stations, process equipment, flanges and valves, as well as gas distribution networks and electrical equipment. The removable TDLAS module extends the camera’s acoustic inspection capabilities with selective methane detection, allowing both leak localisation and methane measurement within the same inspection workflow.

FAQ
Honest answers to important questions
CRY8125M is a special package combining the CRY8125 Ex acoustic imaging camera with a removable TDLAS laser methane detector module. The package is supplied as one certified set with the camera, laser module, batteries, charger, reporting software and case.
The acoustic camera first detects and localises a leak from the ultrasound it produces. The TDLAS module is then pointed at the same location to detect methane and measure its concentration along the laser beam path.
The two methods perform different tasks. Acoustic imaging locates the leak, while TDLAS confirms that the released gas contains methane and provides a methane measurement.
Yes. The acoustic technology detects ultrasound generated by pressurised gas or a vacuum. It is therefore not limited to methane.
Yes. The TDLAS methane sensor is removable and connects to the camera via USB-C. This allows the camera to remain a general-purpose inspection tool when methane detection is not required.
Yes. The camera and TDLAS module have separate Ex certifications. The camera is certified to II 3 G Ex ic IIC T5 Gc and II 3 D Ex ic IIIC T100 °C Dc, while the TDLAS module is certified to Ex ib IIC T6 Gb and Ex ib IIIC T80 °C Db.
The methane sensitivity is 1 ppm×m, with a measurable level of 0–100,000 ppm×m.
The acoustic detection distance is 0.2–200 m. The minimum detectable leak is specified as 0.0028 L/min at 0.5 m and 1.9 bar.
The methane measurement distance is 0.5–60 m. Laser ranging is from 0.03 to 60 m.
Yes. During acoustic inspection, the camera estimates the leak rate and cost. The acoustic image also marks the leak on the live camera view.
The package is intended for applications including oil and gas facilities, chemical and LNG installations, power and utility infrastructure, gas distribution networks, and partial discharge surveys on switchgear and overhead lines.
