Key Features Of FLIR G-Series Optical Gas Imaging Camera

1. Advanced Thermal Imaging with 320 x 240 IR Resolution
With a thermal resolution of 320 × 240 (76,800 pixels) and a thermal sensitivity of <10 mK at 30°C, the FLIR G-Series delivers crisp, high-contrast thermal images. It operates in a 3.2 µm to 3.4 µm spectral range, optimized for hydrocarbon gas detection. The cooled InSb detector and Stirling microcooler provide stable imaging in all environments.

2. Precise Gas Quantification and Measurement Tools
Integrated gas quantification tools allow you to measure leaks in real time with onboard analysis. Capable of detecting CH₄ at <9.6 ppm x m and multiple hydrocarbons at <4 ppm x m, this camera offers onboard delta T, spot meters (up to 10), and area measurement boxes (5 with min/max/avg). Custom temperature ranges from -20°C to 350°C make it suitable for both ambient and process monitoring.

3. Rotatable Touchscreen and Viewfinder Display
The camera includes a rotatable 4″ LCD touchscreen (640 x 480 pixels) and a built-in tiltable OLED viewfinder (800 x 480 pixels), offering flexible viewing angles in tough environments. Onscreen display allows simultaneous IR, visual, and HSM (High Sensitivity Mode) with image overlay and advanced filtering.

4. Radiometric Video, Image Capture, and Streaming
Capture radiometric JPGs, RTRR video files, and stream H.264/MPEG4/MJPEG videos over Wi-Fi or USB. MultiREC mode allows for recording multiple sequences in customizable order. FLIR Ignite cloud compatibility makes it easy to upload and organize data for collaborative inspections or regulatory documentation.

5. Industrial Grade Safety and Connectivity
With hazardous location compliance (ATEX/IECEx, Class I Division 2), the G-Series is engineered for use in explosive environments. It features IP54-rated sealing, shock and vibration resistance, and broad connectivity including USB 2.0, Wi-Fi (2.4 GHz/5 GHz), HDMI output, and Bluetooth. Built-in GPS logs image metadata, and integrated annotations (voice, text, sketch) enhance field documentation.

Why You’ll Love the FLIR G-Series OGI Camera

1. See the Unseen with Confidence
You can now visualize invisible gas leaks and thermal anomalies in real time. The FLIR G-Series’s high sensitivity and spectral tuning ensure that even the smallest emissions are detectable, helping you catch and fix problems before they become costly disasters.

2. Designed for Harsh, High-Risk Environments
Certified for hazardous locations, shock-resistant, and sealed against dust and water (IP54), this camera is built for dangerous industrial zones. Whether you’re climbing platforms or inspecting pipelines, the G-Series is made to survive and perform.

3. Real-Time Quantification Saves Time & Money
Forget estimating leaks by eye. The built-in quantification system tells you exactly how much gas is escaping—making your reports more precise and your repairs more targeted. It also helps you comply with global methane emission reduction standards.

4. Rich Data Capture and Seamless Reporting
Record, annotate, stream, and share—this camera supports radiometric JPEGs, thermal videos, GPS tagging, and more. Upload directly to FLIR Ignite for secure cloud access and reporting, making inspections more collaborative and efficient.

5. Professional Workflow Integration
From touchscreen operation to multiple language support (21+), the user interface is designed for ease and speed. Long battery life, removable SD storage, multi-format video out (HDMI/DVI), and inspection route support ensure it fits smoothly into professional maintenance routines.

How to Use

1. Power Up and Navigate the Display
Start by charging the FLIR G-Series with the included 7.4V Li-ion battery using the provided charger and power adapter. Once charged, press the power button to initiate boot-up—note that it takes about 7 minutes to fully start. The 4-inch rotatable LCD and tiltable OLED viewfinder provide sharp visuals and easy access to menus for thermal settings, video capture, and annotations.

2. Select Thermal Settings and Color Palette
Use the interface to set your desired thermal mode. Choose from palettes like Arctic, White Hot, Black Hot, Iron, Lava, or Rainbow HC for clearer image contrast based on your application. Adjust image resolution, digital zoom (up to 8×), and switch between radiometric and streaming formats such as H.264 or MJPEG for real-time viewing or recording.

3. Perform Targeted Gas or Temperature Detection
Point the camera at the inspection target using the laser spot for centering. The cooled InSb FPA sensor detects even slight variations with <10 mK sensitivity and an accuracy of ±1°C or ±2%. You can capture gas leaks (like CH₄ or hydrocarbons) or heat anomalies using predefined subranges from -20°C to 350°C.

4. Analyze and Annotate Images Onboard
Use built-in tools like 10 spot measurements, 5 boxes, delta T analysis, and live line graphs to examine data directly on-screen. Sketch over IR images, record 60-second voice notes, or type text directly into the image metadata. GPS integration adds precise location to each file automatically.

5. Save, Transfer, or Upload Data
Store your thermal images and videos on the removable SD card in JPEG or .csq formats. Use USB, Wi-Fi, Bluetooth, or HDMI output for transferring files to external devices or for live streaming. You can also connect to FLIR Ignite cloud to auto-upload data wirelessly and ensure secure backups during field operations.

How to Take Care

1. Clean Lenses and Display Gently
Use a soft microfiber cloth to clean the LCD screen, OLED viewfinder, and lens. Avoid liquids or rough materials. Always replace the front and rear lens caps (based on 80 mm or 92 mm) when not in use to protect the optics from scratches or debris.

2. Store Safely in Hard Case
After every session, pack the camera, batteries, lenses, SD card, and tools into the supplied hard transport case. This keeps everything safe from shock, moisture, and dust, especially during transit or long-term storage in outdoor conditions.

3. Avoid Extreme Weather and Sunlight
The device can operate between -20°C and 50°C, but avoid leaving it exposed to direct sunlight or freezing cold for extended periods. Store within the safe range of -30°C to 60°C and avoid high-humidity environments that could affect internal components.

4. Recharge and Rotate Batteries
Charge each 7.4V Li-ion battery fully before use (approx. 2.5 hours per battery). For extended fieldwork, always carry a spare battery. Avoid deep discharges and recharge the batteries every few months even when not in use to prolong battery life.

5. Handle Lenses and Accessories with Care
When switching between 14.5° or 24° manual-focus lenses, do so on a clean, stable surface. Avoid over-tightening. Keep the camera’s mounting threads and internal connectors free of dust. Always use only FLIR-approved parts to maintain warranty and performance.

Safety Tips

1. Never Aim at Human or Animal Eyes
The integrated laser spot should never be directed toward anyone’s eyes. Although low-powered, direct exposure to laser beams or reflections can cause temporary blindness or disorientation.

2. Handle with Both Hands When In Use
Weighing 3 kg, the device is heavy. Always secure the handstrap or neckstrap before operating to avoid accidental drops or arm fatigue during prolonged inspections.

3. Use in Certified Zones Only
The FLIR G-Series is ATEX, IECEx, and ANSI/ISA certified for use in hazardous environments, but always confirm local compliance before use in explosive zones. Refer to Class I, Division 2 guidelines if used near flammable gases or dust.

4. Keep Away from Unauthorized Users
This is an advanced industrial-grade thermal camera. Always keep it stored in a secure place, away from untrained users, children, or curious hands to prevent misuse or damage.

5. Follow RF Transmission Guidelines
When using Wi-Fi or Bluetooth features, be aware of RF output limits (Wi-Fi <17 dBm, Bluetooth <10 dBm). Always turn off wireless modes when operating in RF-restricted or sensitive environments like hospitals or airports.
