CE compliant in accordance with:
Approvals
ATEX Directive 94/9/EC
EMC Directive 2004/108/EC (EN50270:2006)
Notes: Detection performance is temperature and humidity dependent. Listed data is based at 20°C, 50% RH only. Response time is
longer when operating in colder temperatures.
*When operating in Hazardous Area applications the detector must not be operated outside the certified temperature range. See
Certification details for UL, c-UL and ATEX/IECEx certified temperature ranges.
