Description
The GLF314 is a professional-grade, high-sensitivity dual-band infrared gas imaging leak detectorexclusively designed for non-contact, real-time visualization of gas leaks in power systems and petrochemical industries. It fully complies with DL/T 846.6-2018, IEC 60480-2004 and GB/T 22065-2008 standards, adopting an innovative dual-band uncooled infrared focal plane array (FPA) detector that can simultaneously detect SF6 sulfur hexafluoride and CH4 methane without changing filters.
The instrument features an industry-leading 384×288 high resolution and ≤0.1℃ ultra-high thermal sensitivity, enabling it to detect extremely small gas leaks that are invisible to the naked eye. Its proprietary Gas Visual Enhancement Technology (GVETM) significantly improves gas contrast against background, making even the tiniest leaks clearly visible. The innovative dual-display system with a 5-inch rotatable LCD touch screen and high-resolution OLED viewfinder ensures clear visibility even in strong direct sunlight.

FAQ
Q: What is the advantage of dual-band technology compared to single-band gas detectors?
A:
- Dual detection capability: One instrument can detect both SF6 (used in power systems) and CH4 (used in petrochemical and natural gas industries) simultaneously
- No filter changing: Eliminates the need to stop work and change filters when switching between different gas types
- Cost effective: Reduces equipment investment by 50% compared to purchasing two separate single-band detectors
- Versatility: Suitable for multiple industries and applications with a single device
Q: How sensitive is the SF6 gas leak detection?
A: GLF314 can detect SF6 gas leaks as small as 0.001mL/s from up to 50 meters away. This is equivalent to detecting a leak of less than 1 gram per year, which is far below the industry standard limit of 1% annual leakage rate for SF6 equipment.
Q: Can it work in strong sunlight?
A: Yes. GLF314 features an innovative dual-display system with a high-brightness rotatable LCD screen and a high-resolution OLED viewfinder. The OLED viewfinder is specially designed for strong sunlight conditions, providing clear and sharp images even in direct sunlight.
Q: How long does the battery last?
A: The built-in rechargeable lithium-ion battery provides more than 4 hours of continuous operation under normal test conditions. It also supports external DC12V power supply for extended working time.
Q: Can it record videos?
A: Yes. GLF314 supports both radiometric infrared video recording (.raw format, contains full temperature data) and non-radiometric video recording (.avi format). Videos are stored on the 32GB removable TF card.
