Zellweger Impact IR Personal Multi-Gas Monitor

This product is now obsolete. Please contact us in order for us to recommend a replacement to suit your requirements.

Impact infrared sensor version incorporating all of the standard features of the popular Impact Pro portable gas detector range, now including a range of advanced infrared (IR) optical sensors with models available to detect % LEL or % VOL Methane (as well as other Hydrocarbons), and CO2 with long-term stability.

This additional sensor complements the proven electrochemical cell and catalytic bead technology within the Impact Pro range.

Infrared Cells: IR sensors operate by passing infrared light through the gas sample and detecting the change in transmitted light as the molecules absorb the energy to change their vibrational and rotational status. A specific fingerprint can be assigned in the IR spectrum that represents certain gas molecules.

Miniature IR sensors can now be practically incorporated into portable devices; they have the characteristic of a small footprint and relatively low battery consumption making for an ideal sensor for portable use to detect Methane (linear) and other Hydrocarbons at % LEL and % Vol applications.

IR sensors can also be tuned to measure Carbon Dioxide (CO2).
