S-Infra.Sens NDIR gas sensor based on the NDIR technique is an established method to determine the concentrations of gases in complex mixtures. The S-Infra.Sens module uses novel optical components for optimum analysis result. The entire unit can be disassembled for easy maintenance/service. The individual modules are sealed by means of O-ring connections. In order to achieve an optimum adaptation to the required measuring range, the modular design cell lengths can be implemented in the range of 5mm to 250mm. For fast response applications the measuring system delivers a stable result within t90 < 3 seconds @ 1l/min gas flow. The mechanical parts can be built optionally with aluminum or stainless steel. Additionally, the cell wall can be coated with a resistant gold layer, in order to improve the reflection properties for low gas level detection.
