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.
