Notes
■
Exposure to high levels of organic solvents
can damage the sensors.
■
Exposure to gases at levels higher than the
monitor’s range can damage the device.
Recalibrate sensors if they go out of range.
1.
In ppm unless otherwise specified.
2. At 50% of scale (same unit as range).
3. As % of signal read unless otherwise specified.
4. Nominative values in normal use conditions per month as % of scale for zero and as % of
measurement for sensitivity.
5. In seconds at 90% of final value.
6. In °C.
7. Without condensation.
8. Averaged value. In normal conditions. 12 month warranty.
9. All sensors must be protected from air when stored.
10. Time to reach full performance of the sensor after warm-up.
