LSJ TIG10: A Handheld Gas Detection Thermal Imager for Firegrounds and Industrial Leaks

Figure 1. The LSJ TIG10 operated at a live-fire scene. The camera reads heat and gas at a distance — no contact with the source required.

Thermal Imaging and Gas Leak Detection in One Handheld Unit

The TIG10 merges a thermal imaging camera with optical gas imaging in a single handheld device, so responders carry one instrument instead of two when they enter a fire scene or a suspected leak site.

Built on long-wave infrared detection, the camera renders gas movement that conventional cameras cannot show — including methane, sulfur hexafluoride, nitrogen dioxide and sulfur trioxide. The plume, its source and its path appear on screen in real time, narrowing the search from an entire plant area to the specific valve, flange or pipeline.

Because the scan is non-contact, operators hold back from pressurized fittings, toxic plumes and unstable structures. Optical gas imaging is already used to support fugitive-emission monitoring in oil and gas regulation; the U.S. EPA outlines the underlying leak-detection requirements in its oil and natural gas air pollution controls.

A 640×512 Sensor That Reads Smoke-Filled Scenes

At the core of the TIG10 is a 640×512 high-sensitivity infrared detector, which captures 4.3× the thermal pixels of a common 320×240 sensor (327,680 versus 76,800 pixels).

The resolution earns its keep at the moment of entry. Rescue personnel, the seat of a fire and a small leak point remain distinguishable when smoke, steam or low light would wash out a lower-resolution image. A live temperature readout supports fixed-point measurement, letting crews track a hotspot instead of estimating its position.

−20 °C to 1200 °C with Automatic Range Switching

The TIG10 measures across −20 °C to 1200 °C and switches ranges automatically, so one device covers cold leak surveys and fully involved fires without a manual recalibration.

The screen shows maximum, minimum and central-spot temperatures at the same time. Inspectors use the same unit for fire-suppression support, equipment checks and post-incident fire-cause investigation, moving from a cold valve to a hot surface without swapping instruments.

IP67 Sealing and Controls Built for Gloved Hands

An IP67-rated housing, compact frame and oversized keys make the TIG10 operable in water, dust and heat while the operator wears structural firefighting gloves.

The nano-coated screen stays legible under high humidity and high ambient temperature. A laser pointer marks the exact target under discussion, and an electronic compass preserves orientation when smoke removes visual reference points. The ergonomic grip and simplified key layout keep attention on the scene rather than the device.

Where the TIG10 Is Deployed

Fire departments, oil and gas producers, chemical plants, utility and infrastructure inspection teams, and fire investigation units use the TIG10 wherever heat and gas risk occur together.

• ✓Fire departments and emergency response teams — search through smoke, locate hidden fire sources and monitor residual fire.
• ✓Oil & gas operations — visualize fugitive methane and SF₆ leaks along pipelines, valves, flanges and tanks.
• ✓Chemical plants — trace hazardous gas movement without approaching the source.
• ✓Utility and infrastructure inspections — survey overheating equipment and enclosures before failure.
• ✓Fire investigation units — record fixed-point temperature evidence for cause-and-origin work.
