Response time |
90% of final reading (Typical) <15 seconds(pentane) <10 seconds (methane) (normal temperature range) |
Oxygen
The oxygen sensor has built-in temperature compensation. However, if temperature shifts dramatically, the oxygen sensor reading may shift. Zero the device at the work place temperature for the least effect.

0 to 30 vol.% O2* |
Resolution |
0.1 vol.% O2 |
Reproducibility |
0.7 vol.% O2 for 0 to 30 vol.% O2 |
Response time (Typical) |
(90% of final reading) <10 second (normal temperature range) |
Sensor Cross-Sensitivity |
The oxygen sensor has no common cross-sensitivities. |
