Gas analyzers
SIRA UV THT
The SIRA UV THT is a stationary indoor measuring device for real-time determination of the THT (tetrahydrothiophene) content in natural gas. The THT concentration is determined using UV spectroscopy.
Precise measurement of the THT content is necessary to ensure reliable control of the THT level in the natural gas network. The advantage of UV measurement technology lies in its high measurement frequency, which enables accurate control and close monitoring of the THT concentration.
With adjustable measurement frequency, extensive customization options, and virtually maintenance-free design, the SIRA UV THT offers exceptional versatility and reliability
