Methane analyzer APHA-370 THC

hydrogenflue gasfor ambient air

The APHA-370 continuously monitors atmospheric THC, NMHC, and CH4 concentrations using a cross-flow modulated selective combustion type method combined with a hydrogen ion detection method. The APHA-370 employs an independent, internal dry-method sampling device to achieve the highest levels of sensitivity and accuracy. Features The APHA-370 uses a combination of the flame ionization detection method and selective-combustion. This gives it the advantage of the single-detector method plus the ability to perform continuous measurements, free of zero-drift, for THC, NMHC, and CH4. The design gives great stability and high sensitivity (0-5 ppm F.S.) The APHA-370 has a relative-sensitivity correction function for CH4 and NMHC. All the necessary features are built right into a single rack-sized instrument, including a catalytic unit for selective combustion (i.e., an NMHC cutter); a cataytic unit for generating reference gas and auxiliary combustion air (standard); and a sampling pump. The only supplemental gas required is H2.
