GIR-1600 Infrared Optical Gas Imaging Camera

Product Introduction

The HM Instruments GIR-1600 is a professional-grade optical gas imaging (OGI) camera designed for non-contact, long-distance visualization of volatile organic compound (VOC) leaks in petrochemical, chemical, natural gas, and environmental inspection applications. Equipped with a cooled High-Operating-Temperature (HOT) Type-II Superlattice infrared detector operating in the 3.2–3.5 μm spectral band, the GIR-1600 visualizes over 400 VOC species — including methane, benzene, ethanol, and gasoline vapor — as visible gas plumes against background scenes, enabling rapid source identification without requiring inspectors to approach hazardous equipment.

The HOT detector architecture operates at approximately 120 K, compared to the 77 K required by conventional InSb detectors. This higher operating temperature reduces Stirling cooler load, lowers power consumption, minimizes heat output, and extends the cooler motor's service life — translating to longer battery runtime and reduced maintenance frequency in field deployments. The NETD of <10 mK at 25°C and gas detection sensitivity of ≤20 mK place the GIR-1600 in the same performance tier as international OGI cameras priced significantly higher.

Applications

• Petrochemical and refinery LDAR (Leak Detection and Repair) component surveys

• Natural gas wellhead, compressor station, and pipeline inspection

• Chemical plant fugitive VOC emission screening

• Municipal solid waste landfill gas migration detection

• Power plant fuel system inspection

• Environmental enforcement agency inspections

Functional Performance / Features

1. Cooled HOT Type-II Superlattice detector — 320×256 resolution, 3.2–3.5 μm spectral band, operates at ~120 K for extended cooler life

2. NETD <10 mK @ 25°C — industry-leading thermal sensitivity enabling gas visualization under challenging field conditions

3. 400+ VOC species detection — covers methane, ethanol, benzene, gasoline vapor, toluene, propane, butane, and a broad range of hydrocarbons

4. Non-contact long-distance inspection — unlimited observation range; effective detection at 30–100 m under typical field conditions

5. PID/FID wireless integration — links with external quantitative instruments to combine OGI visualization with concentration measurement
