Total Hydrocarbons FID Analyzer

HC51M

Using a proven flame ionisation detector (FID), the analyzer HC51M measures ambient air hydrocarbons (THC, CH4, nmHC) in the range 0-1000 ppm.

Available in 2 versions for the simultaneous and continuous measurement of:
• THC (Total Hydrocarbons)
• THC / CH4 / nmHC (Total Hydrocarbons, methane and non-methane)”

Add to Compare
  • Continuous indoor and outdoor air quality monitoring
  • Stationary and mobile AQMS laboratories
  • Industrial fence-line and field monitoring
  • Measurement of impurities in industrial gases (O2 or CO2)
  • Continuous emissions monitoring (CEM) by dilution
  • Measurement Campaigns and Monitoring Studies…

Application examples:

  • Measurements in the range of 0-1,000 ppm
  • Graphic Liquid Crystal Display (LCD)
  • Interactive menu driven software
  • Auto-ranging
  • User programmable ranges and time averages
  • Built-in storage of 1 year average data
