The World's Sixth Sense™
A groundbreaking uncooled optical gas imaging camera with a low-range 25° lens detects methane, nitrous oxide, propane, sulfur dioxide, and other gas emissions. Capable of both gas detection and radiometric temperature measurement, it is an ideal inspection tool for thermal inspections, oil/natural gas operations, and more!
A groundbreaking uncooled optical gas imaging camera with a low-range 25° lens detects methane, nitrous oxide, propane, sulfur dioxide, and other gas emissions. Capable of both gas detection and radiometric temperature measurement, it is an ideal inspection tool for thermal inspections, oil/natural gas operations, and more!
Capable of both gas detection and radiometric temperature measurement, this OGI camera is an ideal inspection tool for thermal inspections, electric power utilities, oil and natural gas operations, chemical/ manufacturing facilities, the food and agriculture industry, and first responders. It offers unmatched versatility as well as improved visualization of gas emissions and thermal inspections, along with a vibrant, 4" touchscreen LCD, 180° rotating optical block, and eyepiece for convenience in direct sunlight. Additionally, it provides the benefit of built-in thermographic calibrations and the flexibility to detect a wide range of gases by changing lenses.
Maximize efficiency
Locate gas leaks and perform thermal inspections with one camera.
Economical optical gas imaging
Provide every site with one or more cameras with industry-leading features.
Streamline inspections and reporting
Work easier with the ergonomic design, rapid-reporting features, and tools to organize findings in the field.
