OC-1000 Portable multi gas detector for CO/O2/H2S/LEL/CH4

OC-1000 Portable multi gas detector for CO/O2/H2S/LEL/CH4. Description: OC-1000 portable multi gas detector with the inner pump to detect the gas composite concentration data in different working place. Our engineer design it with 6 sensors at most: one is default of the Temperature & Humidity sensor, so if users only need to detect the gas, it can detect 5 gas type at most, users can choose 2 ...

Explosionsgrenze – Wikipedia

Gemische aus brennbaren Gasen, Dämpfen oder Stäuben mit Luft und damit dem in ihr enthaltenen Sauerstoff sind bei bestimmten, stofftypischen Mischungsverhältnissen explosionsfähig. Diese Mischungsverhältnisse bestimmen den Explosionsbereich, der durch seine zwei Explosionsgrenzen, der oberen und der unteren Explosionsgrenze (OEG ), beschrieben wird:

Safety - What is %LEL / %UEL and PID and PPM? - Lower ...

Therefore, 100% of LEL is 14,000 ppm of gasoline, 10% of LEL is 1,400 ppm of gasoline and 1% of LEL is 140 ppm of gasoline. 140 ppm of gasoline is the lowest amount of vapor that the LEL monitor can "see." Gasoline has a TWA of 300 ppm and a STEL of 500 ppm; this does not make LEL sensors well suited for measuring gasoline vapors because they simply don't provide adequate resolution. LEL ...

What does "methane %LEL equivalent" mean?

Low Alarm (%LEL) = 10 (based on CH4) High Alarm (%LEL) = 20 (based on CH4) UEL is the Upper Explosive Limit at which a gas concentration is too high it is not explosive. However, for safety purposes, we use only the LEL. A catalytic sensor is 0-100% LEL, which means it is 0-5% vol. (or 50,000 ppm) equivalent to Methane.

Units of Measure: How to convert LEL to PPM, PPB or %BV

· If we use methane (CH4) as an example, the LEL (lower explosive level) of methane is generally considered to be 5% by volume (5% bv). That means the mixture is too lean to burn if there is less than 5% methane present. But at 5%, we can burn or explode if there is an ignition source. So we call 5% bv methane the same as 100% LEL. 5% methane is 100% of the explosive concentration. …

Flammability limit - Wikipedia

In addition, a concentration above the LEL can be created suddenly from settled dust accumulations, so management by routine monitoring, as is done with gases and vapours, is of no value. The preferred method of managing combustible dust is by preventing accumulations of settled dust through process enclosure, ventilation, and surface cleaning. However, lower flammability limits may be ...
