How reliable are CO2 measurements? - Skeptical Science

Given oxygen makes up over 20% of the atmosphere whereas CO2 is a minor trace gas, the means that would have to be applied so that such a minor trace gas will become evenly distributed could be expected to apply to all other elements present in the atmosphere, including heat which always seeks to find equilibrium. doug_bostrom at 09:49 AM on 18 May, 2010.

The difference between sensor error and uncertainty ...

· In simple terms, measurement uncertainty as stated in a datasheet is taken as the range of the 95 closest measurements to the average (mean) of 100 measurements. So if the 95 measurements fall into a range of plus °C and minus - °C away from the 100 measurement mean, than the sensor uncertainty as written in the data sheet will be ±0 ...

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 ...

LMP91051 NDIR CO2 Gas Detection System -

LMP91051 NDIR CO2 Gas Detection System ... below shows the basic NDIR gas sensor working principle. Figure 1. NDIR Gas Sensor Principle Gas molecules will absorb radiation energy from the lamp emission. Absorption follows the Lambert-Beer law: I = I0 * e-kcl Where I is the transmitted IR intensity at the thermopile detector side, I0 is the initial intensity at the IR source, k is the gas ...

Gassensor – 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.

Chapter 2 Electrochemical Sensors

For example, a low concentration gas sensor with very high sensitivity uses a coarse-porosity hydrophobic membrane and less restricted capillary to allow more gas molecules to pass through to produce enough sig- nal for better sensitivity. However, this design also al-lows more of the electrolyte’s water molecules to es-cape out to the environment. In other words, an elec-trochemical sensor ...
