Perform various gas detection tests and thermal inspections
Uncooled gas detection camera solution


Developed based on the existing GF77 camera for methane gas detection, the GF77 Gas Find IR series now offers two types of lenses to allow users to find a wider variety of gases with one camera.

FLIR announced on the 27th that it has developed the GF77 Gas Find IR series based on the GF77 camera. The GF77 Gas Find IR series offers two types of lenses to enable a wider range of gases to be found with a single camera.

This newly launched product is an uncooled gas detection camera solution that can be used by chemical and industrial manufacturers, power utilities, natural gas supply chains, food and agriculture, and public safety facilities to perform a variety of gas detection and thermal inspections. New capabilities have been added to visualize new types of gases, including sulfur hexafluoride, ammonia, and ethylene, and options for FLIR Thermal Studio Pro and FLIR Route Creator have been added to accurately display measured temperature values.

The GF77 Gas Find IR series offers a wider temperature detection range, from -20°C to 500°C, with improved accuracy from +/- 5°C to +/- 3°C over the entire temperature range. The optional onboard routing feature, Route Creator, allows end users to pre-plan routes listing the equipment and facilities to be inspected at each site, streamlining surveys and avoiding unexpected errors or omissions. Additionally, the reporting add-on, Thermal Studio Pro, facilitates the creation of comprehensive final reports.

Additionally, it is ergonomically designed for ease of use and can be calibrated for infrared temperature measurement. Tank water levels can also be checked without changing lenses, allowing for easy preventative maintenance, such as checking for electrical or mechanical issues.

The GF77 Gas Find IR series offers two lenses: a standard 25° field of view (low range) lens or a 6° telephoto lens. The low-range lens has a 7–8.5 µm wavelength filter to visualize methane, nitrous oxide, sulfur dioxide, R-134a and R-152a, while the high-range lens filters the 9.5–12 µm wavelength to visualize sulfur hexafluoride, ammonia and ethylene with a built-in filter.

Professional users can choose the lens combination they need from the GF77-LR, GF77-HR or GF77, which includes both low- and high-range lenses.

Meanwhile, FLIR Service Centers provide a calibration service for newly purchased lenses to customers who already own a GF77 and need to expand its functionality.
