DEC.LEL™ • what is a LEL detector?

An LEL detector, or LEL meter, is a process analyzer (DEC.ATX™) that quantifies dangerous levels of combustible gases or solvent vapors in the air, expressed as a percentage of the Lower Explosive Limit (LEL). It serves as an essential element within a complete gas detection system.

DEC.LEL™ • measured values (%)

Explosivity is typically measured in %LEL (0-100% LEL), where 100% means the gas concentration has reached the lower explosive limit and became explosive.

DEC.LEL™ • key terms

  • LEL: Lower Explosive Limit: the concentration of a combustible gas or vapor in air below which an explosion or flame cannot occur due to insufficient fuel.
  • UEL: Upper Explosive Limit: the concentration of a combustible gas or vapor in air above which an explosion or flame cannot occur due to insufficient oxygen.
  • Sensitivity: refers to the degree to which a gas detector senses changes in gas concentration.
  • Detection accuracy: refers to the comprehensive performance including the correctness, accuracy, repeatability of the value displayed by the gas detector (or the value indicated by the measurement result).
  • Response time: When the concentration of the test gas changes instantaneously, the time required for its indicated value to be controlled within a specific range of the final value.
