FAQ: Frequently Asked Questions
Why is oxygen (O₂) concentration monitoring important in indoor environments?
Oxygen monitoring helps identify atmospheres with concentrations below or above normal levels in air. O₂ depletion can occur, for example, due to oxygen consumption, displacement by other gases or insufficient ventilation, while oxygen-enriched atmospheres can increase combustion hazards. O₂ measurement is therefore important for monitoring environmental conditions in technical rooms, industrial environments and other potentially critical spaces.
In which environments and applications is O₂ concentration monitoring useful?
Oxygen measurement is particularly relevant in confined spaces and environments where processes, materials or other gases can alter normal O₂ concentrations. It can be used in technical and industrial areas, waste-management facilities and other enclosed environments where atmospheric conditions need to be monitored over time. In confined spaces, oxygen testing is one of the fundamental elements of atmospheric assessment.
What are the main features of LSI LASTEM oxygen sensors?
LSI LASTEM O₂ sensors are designed to measure oxygen concentration in indoor environments and use electrochemical cell technology. The range provides a measuring range of 0–25% O₂, an operating temperature from -30 to +55 °C and an indicative sensor life of 3 years. Configurations are available for both portable applications and fixed installations.
How can LSI LASTEM O₂ sensors be integrated into a monitoring system?
LSI LASTEM O₂ sensors can be used for measurement surveys or continuous monitoring. Models are available with mV output and MiniDIN connectors for M-Log data loggers, as well as versions with 4–20 mA and RS485 Modbus that can also be used with third-party acquisition systems. O₂ can also be monitored together with other gases and environmental parameters to provide a multiparameter assessment of atmospheric conditions.
