Remarks:
* RAEGuard Lite will provide users more communication interfaces and gas types in the future, such as wireless etc. For
availability, please contact Honeywell Analytics.
*** Catalytics sensor can work continuously at -40°C ~ +70°C; toxic and Oxygen sensor can work continuously at -20°C ~ +55°C,
intermittently at -40°C ~ +70°C (The accuracy and response time of sensors operating in this temperature range will be affected,
and long-term operation may lead to sensor sensitivity decline or even damage.)
**** The performance characteristics of the products mentioned above are typical results tested in an environment with a
temperature 20°C and a humidity of 50% RH. When calibrating, use the calibration cap and recommended flow for detection. If
the sunshade/deluge is used instead or the detection is carried out at low temperature, the response time will be slowed down.
