Ambient HC Monitor

APHA-360

Features


The APHA-360 uses a combination of the flame ionisation detection method and selective-combustion. This gives it the advantages of the single- detector method plus the ability to do continuous, zero-drift free measurements of THC, NMHC, and CH4. The design gives great stability and high sensitivity (F.S. 5 ppm). The APHA-360 has a relative-sensitivity correction function for CH4 and NMHC.


A catalytic unit for generating reference gas and auxiliary combustion air is standard equipment in the APHA-360.


All the necessary features are built into a single rack sized instrument, including a catalytic unit for selective combustion (i.e., an NMHC cutter); a catalytic unit for generating reference gas and auxiliary combustion air; and a sampling pump.

The only supplemental gas required is hydrogen.
