FLIR GF77a
气体泄漏可视化连续监测解决方案
Product Variations
FLIR GF77a是FLIR推出的首款非制冷型自动泄漏检测热像仪，专门针对甲烷气体可视化而设计。这款经济实惠的固定式热像仪解决方案为上游和中游气体处理者、生产者或经营者提供持续监控潜在危险、难以察觉的甲烷泄漏所需的功能。FLIR GF77a外形小巧且重量轻盈，搭载FLIR技术，如高灵敏度模式（HSM），以增强气体可视化效果。GF77a有助于油气公司维护贵重资本设备，避免产品损伤，符合减排标准，确保操作规程更安全。
连续监测天然气泄漏
为持续监控应用提供高灵敏度模式、远距离电动调焦和便于第三方集成的开放式架构等功能
通过光谱筛选的方式检测甲烷气体，提高工人安全性，更少的到场检查即可识别泄漏位置
GF77a兼容RTSP、GigE和ONVIF协议，连接灵活，可满足众多工业通信需求，连接至网络可实现连续泄漏监测
