VOC Sensor Capabilities and Limitations Application Note ...

The VOC sensor will show elevated levels when ethyl alcohol is present and signal the HVAC system to increase ventilation, but the sensor cannot provide a specific ppm measurement of ethyl alcohol so that the user can document compliance to OSHA exposure limits. The VOC sensor was designed to monitor common indoor air quality contaminants only. There are several gases that will affect the sensor …

About TVOC and the Laser Egg+ Chemical

VOC concentrations are consistently higher indoors (up to 10 times, according to the EPA) than outdoors and are found in common household products and furnishings. TVOC, or total volatile organic compounds, is a catchall term used to describe the overall level of chemicals present in your air.

Acceptable and Dangerous Gas Levels in Confined Spaces

· Lower Explosive Limit ... Methane, for example, has an LEL of 5% vol and a UEL of 15% vol. Methane combustion is possible when the gas level is at or above 5%, but below 15%. Here is a list of common combustible gases and their lower explosive limits. Gas detectors display a gas''s presence as a percentage of its LEL. An atmosphere free of methane would show 0% LEL on the gas detector, …

For example, the VOC head is calibrated against Isobutylene and is being used to measure the concentration of heptane. The reading in ppm of Isobutylene is 10ppm. Therefore the concentration of heptane is 10 ppm x = 17 ppm. The accuracy of the correction factor is < ± 30%. The VOC sensor can also be used to qualitatively indicate the total VOC level. The

VOC Limits | California Air Resources Board

Table of VOC Limits (Excel) There is sometimes confusion over the terms "VOC regulatory" and "VOC actual" as used by CARB. "VOC regulatory" is the same as the term "VOC coating" used in many local air district rules, which is equivalent to the term "VOC, less water and exempts." "VOC actual" is the same as the term "VOC material" used in district rules, which is equivalent to saying "VOC ...

7 Main Types of Level Sensing Methods – How do they differ?

· Ultrasonic sensors measure levels by calculating the duration and strength of high frequency sound waves that are reflected off the surface of the liquid and back to the sensor – the time taken is relative to the distance between the sensor and the liquid. The length of time in which the sensor takes to react is affected by various elements in the atmosphere above the media such as ...
