SO2, NOx, CO, CO2 NDIR cross flow modulation

HCl adsorption spectroscopy in IR zone

TOC FID

In-situ measuring technology

Automatic measuring system (AMS) where the measurement is carried out directly in the gas duct, without sampling from

the process. If the measurement is undertaken across the diameter of the exhaust gas duct, then pollutants are detected

in a representative manner to a large extent. Refer to cross duct.

Specialty Equipment gas distribution system used at workplace

HiQ REDLINE® Specialty gases product line for high purity gases and

calibration mixtures

• Two stage cylinder regulators with stable outlet pressure equipped

with shut-off valve, tight membrane made from Hastelloy® and

the stainless steel body for corrosive mixtures components.

• The Semiautomatic gas supply panel with switch from empty to full

cylinder without interrupting of the gas flow and signal alarm

box announcing when cylinder is empty.

• The point of use as a second stage of the gas supply system for the

final working pressure adjustment.
