CO2 Gas Sensor User Manual – Vernier

The CO 2 Gas Sensor refreshes its reading every second, but typical changes in experiments are so gradual that the recommended sampling rate is 4 seconds per sample or slower. Gas must diffuse through the holes in the sensor tube before the sensor detects any changes in concentration. Because diffusion of gases is a slow process, there can be delays in the readings. To collect data in a ...

Kohlenstoffmonoxid – Wikipedia

Kohlenstoffmonoxid (fachsprachlich Kohlenstoffmonooxid, gebräuchlich Kohlenmonoxid) ist eine chemische Verbindung aus Kohlenstoff und Sauerstoff mit der Summenformel CO. Kohlenstoffmonoxid ist ein farb-, geruch- und geschmackloses sowie toxisches Gas. Es entsteht unter anderem bei der unvollständigen Verbrennung von kohlenstoffhaltigen Stoffen bei unzureichender Sauerstoffzufuhr.

Wie Sensoren für CO2-Leckageerkennung Leben retten können ...

· Denn unterschiedliche Gerätedesigns können eine Auswirkung darauf haben, wie schnell das Gas zu CO 2-Sensoren gelangt. Ein Sensor kann beispielsweise direkt der überwachten Atmosphäre ausgesetzt werden und somit eine schnelle Reaktionszeit bieten. Im anderen Fall wird das Gas beispielsweise durch ein Kapillarröhrchen zum Sensor geführt, wodurch sich die Reaktionszeit …

Carbon monoxide detector - Wikipedia

The gas sensors in CO alarms have a limited and indeterminable life span, typically two to five years. The test button on a CO alarm only tests the battery and circuitry, not the sensor. CO alarms should be tested with an external source of calibrated test gas, as recommended by the latest version of NFPA 720. Alarms over five years old should be replaced but they should be checked on ...

Carbon Monoxide Sensor Cross-Sensitivities Alcohols, VOCs ...

CO sensors can become saturated with target gas CO. If enough CO enters the sensor beyond maximum range (that listed in the instruction manual), the sensor is unlikely to be able to process all applied gas. When this scenario occurs, the electrolyte becomes saturated. A saturated sensor will continue to show high gas readings until the gas can be processed from the electrolyte. If saturation ...
