CO2. E+E's years of experience in sensors and thin-film technology lead to highest quality non-dispersive infrared (NDIR) CO2 measuring cells. The cells with gold-plated light path are assembled in state-of-the-art clean rooms and represent the prerequisite for highly accurate and long term stable CO2 …
A carbon dioxide sensor or CO 2 sensor is an instrument for the measurement of carbon dioxide gas. The most common principles for CO 2 sensors are infrared gas sensors and chemical gas carbon dioxide is important in monitoring indoor air quality, the function of the lungs in the form of a capnograph device, and many industrial processes.
NDIR is an industry term for "nondispersive infrared", and is the most common type of sensor used to measure carbon dioxide, or CO2. An infrared (IR) lamp directs waves of light through a tube filled with a sample of air toward an optical filter in front of an IR light detector. The IR light detector measures the amount of IR light that passes through the optical filter. The band of IR ...
When CO is detected, the carbon monoxide alarm’s sensor triggers an alarm to alert you. If you’re unsure if the alarm is working, test it by checking the wall outlet’s power or batteries. Why is my carbon monoxide detector beeping every 30 seconds? Carbon monoxide detector beeping intermittently can signal different alerts. Check your detector’s manual. If your alarm sounds every 30 ...

The eSense LEED Fresh Air Indicator (FAI) is a simple, low-cost and maintenance-free carbon dioxide monitor designed to be installed in areas like office buildings or classrooms where the carbon dioxide levels need to be monitored for indoor air quality. An audible and visual signal indicate when recommended indoor carbon dioxide levels are exceeded. The LEED EQ-Credit 1 Requirements ...
PreSens optical carbon dioxide sensors have a measurement range from 1 to 25 % CO 2, which is perfectly suited for culture monitoring and physiological CO 2 sensor foils for 2-dimensional visualization of CO 2 distributions are available for measurements in trace (0 – 1 %) and medium (1 – 25 %) CO 2 range. Our CO2 sensors do not consume carbon dioxide during the ...
Red flashing light and no sound: Carbon monoxide detected. Move to fresh air as soon as possible. The alarm will occur until CO levels drop. Red flashing light and beeping every 5–60 seconds: Dangerous levels of carbon monoxide detected. Move to fresh air immediately. No lights and no sounds: Detector is not receiving power.

· The flashing green light on a carbon monoxide alarm is unique to each model and brand, so it's important to check with the appropriate company or user guide to verify the meaning. A constantly flashing green light can mean nothing more than proper functioning if the light has always been there. This means that it would be impossible to rid the alarm of the flashing light completely. Note that ...
