NDIR sensors are most often used for measuring carbon dioxide. [2] The best of these have sensitivities of 20–50 PPM. [2] Typical NDIR sensors cost in the (US) $100 to $1000 range. NDIR CO 2 sensors are also used for dissolved CO 2 for applications such as beverage carbonation, pharmaceutical fermentation and CO 2 sequestration applications.
A carbon dioxide recorder (or CO 2 recorder) is a machine that can record the level of carbon dioxide at different times. It is more sophisticated than a carbon dioxide detector which only has to indicate the presence of carbon dioxide. There are three main types of carbon dioxide recorder: chemical, physical, and electrical.
Carbon dioxide sensors are being installed into buildings as part of demand-controlled ventilation systems. Sophisticated gas sensor systems are being researched for use in medical diagnostic, monitoring, and treatment systems, well beyond their initial use in operating rooms. Gas monitors and alarms for carbon monoxide and other harmful gases ...
The placement of the sensors should be able to provide an accurate representation of the space, usually placed in a return duct or on the wall. [5] As the sensor reads the increasing amount of carbon dioxide levels in a space, the ventilation increases to dilute the levels.
A detector measures the energy after the infrared energy has passed through the gas to be measured. This is compared to the energy at reference condition of no absorption. Many analyzers are wall-mounted devices intended for long-term, unattended gas monitoring. There are now analysers that measure a range of gases and are highly portable to be ...
Magnetic smoke door holders and retainers are wall-mounted solenoids or electromagnets controlled by a fire alarm system or detection component that magnetically secures spring-loaded self-closing smoke-tight doors in the open position.
