Total Hydrocarbon Analyser - THC 8000
Continuous analysis of THC in PPM and PPB level
Pattern of Approval Russia | Pattern of Approval China (all certificates)
General
Our THC Analyser (THC 8000) is a continuous analytical system that measures the total hydrocarbon (THC) in PPM level in various gases, such as Oxygen, Air, Carbon Dioxide, Nitrogen, Argon, Helium, Hydrogen, Krypton or Xenon.
Principle
The THC Analyser (THC 8000) module is composed of a flame ionization detector placed in a temperature regulated chamber and coupled with a continuous analysing technology.
Burning of the components containing hydrocarbons by the hydrogen flame generates an ion current proportional to the impurities introduced into the gas to be analysed.
This THC Analyser is a standard 19 inch rack module, 4U in height and 450 mm in depth.
One analog 4-20 mA output provides the total concentration of hydrocarbons impurities.
