Flir expands its K-series thermal cameras line

Flir has announced the launch of its K75 and K85 thermal cameras designed for firefighting operations.

According to Flir, the models feature higher resolutions, single-range dynamic gain, and wireless connectivity for configuration, live streaming, training, and data downloads.

The company stated that the new units replace earlier models in the K-series, with the K75 (320 × 240) replacing the K33 and K45, and the K85 (640 × 480) replacing the K53 and K55.

Flir explained that these updates are intended to enhance situational awareness, streamline use, and support decision-making from initial call to post-incident review.

Features of the new cameras

Flir reported that the K75 and K85 both provide up to 640 × 480 resolution for thermal imaging and include a simplified interface with a single-range view.

The company added that this avoids interruptions that can occur when switching between high and low-gain modes.

It explained that both devices retain the K-series pistol-grip design, include wireless connectivity, and support the Flir Responder app for training and data management.

Flir indicated that the cameras are supplied with two batteries, charger, power supply, USB cable, carabiner strap, and retractable lanyard, with optional accessories including a hard transport case and in-vehicle charger.

Durability and design

Peter Dekkers, Director of Business Development at Flir, said: “The K75 and K85 are engineered for frontline firefighting with their rugged IP67-rated construction, 2-meter drop resistance, and outstanding high-heat performance.

“Our engineers have optimized these next-generation cameras for reliable thermal visibility in low-light, no-light and smoke-obscured environments, benefitting not just fire departments, both those in industrial safety, maritime safety and defence.

“Users will discover that quality is set to the highest professional standards, backed by over 10 years of proven design with previous-generation K-Series sensors.”

Application-specific modes

Flir explained that the new models include application-based modes for each phase of operations.

The organisation outlined that preparation is supported by wireless configuration and streaming, while scene arrival benefits from a search mode that contrasts temperatures between 80 and 200°C.

It added that fire attack operations use a single range of −20 to 650°C, while an overhaul mode highlights hotter areas with red gradients and tracks temperature over time.

The company noted that the cameras also feature basic, high-heat, and white-hot modes to assist with smoke diving, offensive firefighting, and training requirements.

Technical specifications

Flir reported that both cameras have a sensitivity of less than 60 mK at 30°C, a 53° × 40° field of view, and 30 Hz image frequency.

The organisation explained that the cameras are delivered with supporting accessories to enable immediate deployment.

It added that the design includes fewer sharp edges to reduce soot and dust accumulation during clean-up.

Relevance for fire and safety professionals

The introduction of the Flir K75 and K85 provides updated options for fire departments seeking imaging tools for incident response.

The new features, including wireless data management and single-range imaging, are intended to support firefighters during decision-making.

For fire and safety professionals, the changes reflect ongoing development in thermal imaging to match operational and training needs.
