Hello! Today we cover the GasTiger 2000 configured for THT (tetrahydrothiophene) odorant and related organic measurements.

The GasTiger 2000 measures many toxic gases. The internal pump was upgraded to move about 1 L/min reliably—important for representative samples.

What is THT (odorant)?

① LNG (liquefied natural gas) supplied to homes is cleaned of dust, sulfur, nitrogen, and other impurities—odorless by design. Because leaks are hard to notice, distributors add a trace of THT as an odor marker.

② LPG (liquefied petroleum gas): when LPG feeds fuel cells, removing THT from the fuel stream can be mandatory for process chemistry.

For everyday LNG service, sulfur-based odorants are blended in; a leak is often noticed first as the pungent mercaptan/sulfur odor rather than the methane itself.

Only about 13–14 mg/m³ is injected—well below harmful human exposure when used as designed. Sulfur species can accelerate corrosion, so plants invest heavily in desulfurization systems.

Because THT confirms leaks, use alarm functions actively for management.

Beyond THT, GasTiger 2000 accepts many other toxic channels—examples include phosgene-class sensors, toluene, VOCs, HF, H₂S, NH₃, hydrogen, and more (exact cartridge depends on chemistry—consult us before ordering).
