These factors only apply to gas concentrations expressed in % volume terms and up to 2.5%vol. These factors may vary from
sensor to sensor with tolerance of ± 25% deviation.
Note:
LEL correlation-factor accuracy may change without notice and is impacted by exposure to sensor inhibitors or poisons,
sensor aging, the gas-detection applications and environment, and other factors. Calibrate instruments using the intended target
gas when feasible and validate correlation factors as needed.
