Ambient Nitrogen Oxides (NOX) Analyzer

IME SA provides a wide range of gas analyzers exclusively dedicated to Air Quality Monitoring, making the offers according to the gases you intend to analyze.

 

The NOX analyzer uses a combination of the dual cross flow modulation type chemiluminescence principle and the referential calculation method to continuously measure the NO2, NO3 and NOx concentrations.

 

It has an internal sampling device to achieve the highest sensitivity and accuracy levels, requiring no need for supplemental gas.

 

IME SA usually integrates the NOX analyzer in its mobile or fixed monitoring stations offering a complete solution for Air Quality Monitoring and analysis.

 

 MEASURING PRINCIPLE:

 

Cross flow modulation type, according the reduced pressure chemiluminescence (CLD).

 

FEATURES:

 

Detector and innovating optical system gives great stability and extremely high sensitivity (o.1 ppm of Full Scale);

Includes a dryer unit with an automatic recycle function to provide dry ambient air as the ozone source. This makes long-term continuous measurements possible;

The detector uses a silicon photodiode sensor to reduce size and prolong working life;

All the necessary features are built right into a single rack-sized unit, including a reference gas generator, as ozone-source drier unit as ozone decomposer, as a sampling pump;

No supplemental gas is required.

 

MEASURING RANGES:

 

Standard Range: 0 - 0,1/0,2/0,5/1 ppm;

Optional Ranges: 4 ranges selectable from 0 -10 ppm within 10 times the range ratio.

 

REPEATABILITY/LINEARITY:

 

±1,0%.

 

OTHER FEATURES:

 

Sample gas flow rate of approx. 0.8 L/min.;

Indication of measured value, range, alarm and maintenance screen;

Alarms: During AIC, zero calibration error, span calibration error, temperature error in converter...;

On-screen messages are available in four languages: English, German, French and Japanese.
