What is the detection range of combustible gas detection alarm
The alarm value of the combustible gas alarm system is set as follows: the lower limit defaults to 25%lel (adjustable from 5%lel to 40%lel); the upper limit defaults to 50%lel (adjustable from 10%lel to 100%lel).
The setting basis is as follows: the measurement range of the combustible gas alarm is 0-100%LEL, and the false alarm is generally set between 15%lel-25%lel according to national regulations.
