概述

CO2 CO N2O CH4 CnHm* CF4 SF6 H2O

The RITTER MultiGas Sensors NDIR Module (non-dispersive IR sensor) has been specially developed for use in high-quality gas analysis. In the design phase special emphasis was placed on high stability and a low detection limit. These goals could be fully achieved by using high-performance light-emitting diodes (IR-LED) and thermal micro-radiators which were adapted to the requirements of gas detection. In the spectral range from 2 μm to 12 μm, carbon dioxide, carbon monoxide, hydrocarbons, water vapor and sulfur hexafluoride can be safely detected down to the ppm range with this innovative sensor platform.

The various photometric components such as detectors, emitters, measuring sample cell, etc. will be assembled user-specifically in a high-quality tabletop casing by RITTER.

Recalibration

  • Readjustment of the zero-point is recommended once a week.
  • Contamination of the measuring cuvette can lead to shifting of the end-point. Due to the integrated filter, re-adjustment of the end-point is generally not required – but can be performed once a year.
  • Additionally, cartridges filled with an inert and the respective test gas for recalibration of the zero and end-point can be provided.
  • Long-term drift is < 1% of Full Scale (F.S.) / 24 h.
