Breakthrough Technology

Hummingbird’s advanced single-beam, single-wavelength Infrared sensor technology offers highly accurate and reliable measurements of methane (CH4). The Photometric technology uses Infrared light to provide CH4 measurements, using specific wavelengths of Infrared energy to cause the bonds within the gas molecules to vibrate.

As different gas molecules are excited by different wavelengths, they absorb energy from Infrared light at their specific wavelengths when it passes through the gas sample making it possible not only to detect and measure the presence of CH4, but also to gain an indication of the gas concentration in the sample.
