GFS Series
Sulphur Dioxide Analyzer
Continuously measures the concentration of trace ambient
sulphur dioxide using ultraviolet fluorescence method.
GLN Series
Nitrogen Oxides Analyzer
Continuously measures the concentration of trace ambient
nitrogen using chemiluminescence method.
GUX Series
Ozone Analyzer
Continuously measures the concentration of trace ambient
ozone using ultraviolet photometeric method.
GFC Series
Carbon Monoxide Analyzer
Continuously measures trace carbon monoxide
concentration in ambient air by gas filter
correlation method.
GHC Series
Non-methane Hydrocarbon Analyzer
Separates hydrocarbons in ambient air into methane and
non-methane hydrocarbons by gas chromatography then
measures their concentrations by a flame ionisation
detector.
Carbon Monoxide
Analyser GFC-311
This analyser operates on the principle of gas filter
correlation method specified by US EPA (continuous
analyser for carbon monoxide in ambient air). Carbon
monoxide in ambient air is measured under stable
conditions.

Particulate Monitor
Model: FPM-222/223
This equipment operates on the principle of Beta ray
attenuation. The Beta ray attenuation method measures
particle mass without the effects of shape, size or
color of the suspended particulate matter. The equipment
includes a PM10 inlet and PM2.5 WINS Impactor or BGIVSCC
cyclone. By connecting a PC, various functions including
self-diagnosics, reading and storage of data
(measurement value, spancoefficient, alarm information)
are available. By connecting the network unit, data can
be remotely acquired through a modem.
