Room Air Quality (VOC) Transmitters QRT 24-series

Detectable Gases:

• Mixed gases, vapors of alcanoles, cigarette smoke, automobile exhaust gases, exhaled breath, combustion smoke (wood, paper, plastics).
• Compounds of alkanes, alkenes, aromatics, terpenes, halogenated hydrocarbons, esters, aldehydes, ketones, and natural VOCs like terpenes and isoprene.
• VOCs from construction chemicals (coatings, adhesives, sealants), furniture, cleaning products, office chemicals, and floor coverings.

Service Life:

• More than 60 months under normal load conditions.

Sensitivity Ranges:

Three selectable ranges using DIP switches:

• LOW: Low noxious gas contamination
• MEDIUM (Default): Medium noxious gas contamination
• HIGH: High noxious gas contamination

QRT 24 (Standard Version):

• Selectable outputs: 0-10 Vdc, 4-20 mA, or 0-20 mA.
• Potential-free changeover contact for switch output.
