Gas Unit- Meaning and Conversion of PPM, LEL& VOL-Winsen

18/09/2017· The relationship between the three units: In normal cases, ppm is used for accurate measurement; LEL is used for explosion test; magnitude of VOL is the largest of the three units. For example, lower limit of explosion of methane is 5% VOL, so 10% LEL methane gas has the following correspondence: 10% LEL = 5000ppm = % VOL

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 ...

Gas Sensor - an overview | ScienceDirect Topics

Gas sensors are generally understood as providing a measurement of the concentration of some analyte of interest, such as CO, CO 2, NO x, SO 2, without at this point dwelling on the plethora of underlying approaches such as optical absorption, electrical conductivity, electrochemical (EC), and catalytic bead (see Section 3). However, and as discussed in Section 2, many other gas sensors ...

CO2 Gas Sensor -

The CO 2 Gas Sensor measures gaseous carbon dioxide concentration in units of parts per million, or ppm. In gaseous mixtures, 1 part per million refers to 1 part by volume in 1 million volume units of the whole. A concentration of 600 ppm for CO 2 would simply mean that there are 600 L of CO 2 gas for every 1,000,000 L of air (or mL of CO 2 per 1 L of air). As a comparison, the level of ...

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 ...
