Cells with a grey background: gases recommended for calibrating the detector
Table 3 : Calibration coefficients of explosive gases for catalytic detectors
with a 4F sensor.
Example
Calibration of an "acetone" detector with a calibration gas of 1% volume butane
Value to be displayed:
1% (𝑖𝑛𝑗𝑒𝑐𝑡𝑒𝑑 𝑏𝑢𝑡𝑎𝑛𝑒)
1.5% (𝐿𝐸𝐿 𝑏𝑢𝑡𝑎𝑛𝑒)
x 100 x 0.90 (butane/acetone coefficient) = 60 % LEL
Note:
LEL values vary according to the source.
Coefficients are accurate to ± 15%.
