ITR 498 | Infrared Gas

Product catalog summary

Overview: The document provides technical specifications and applications for the ADOS ITR 498 Infrared Gas Analysis System, which utilizes non-dispersive infrared analysis to measure gas concentrations.

Specifications:

Test Principle: Non-dispersive infrared analysis.
Measurement Range: 0 – 5000 ppm to 0 – 100 Vol.% CO2.
Response Time (t90): Less than 20 seconds.
Linearity Error: Less than 2% of range full scale deflection (f.s.d.).
Accuracy: Less than ±3% f.s.d.
Long-term Drift: Less than 0.5% per month of range f.s.d.
Ambient Temperature: -20 °C to +45 °C.
Protection Class: IP 54.
Voltage Supply: 12 – 25 V DC, 230V/115 V AC, 12 V Battery.
Power Consumption: 2 VA for transmitter, 9 VA for test unit and hand-held tester (charge).
Battery Life: Over 8 hours on charge.
Outputs: RS 232, 4 – 20 mA, Floating contacts.
Dimensions and Weight: Vary by component, with weights ranging from 500 g to 910 g.

Applications:

Monitoring ventilation and air conditioning in areas with carbon dioxide bottles.
Monitoring ventilation in fruit storage rooms.
Regulating climatic conditions in large offices or stores.
Monitoring maximum concentration at workplaces according to TRGS 900.
Monitoring carbon dioxide fire extinguishing systems.
Analyzing flue gases and monitoring production processes.
Optimizing chemical processes.

Method of Operation: The system uses wide-band infrared radiation that passes through measurement and reference filters to determine gas concentration via absorption bands.

Accessories: Includes gas extraction, filter, gas purifier, gas cooler, signal horn, warning lamps, banners, plotter, and ventilation control accessories. Additional accessories are available upon request.
