FAQ
How often should calibration be performed?
Most users calibrate every 6–12 months depending on field experience and site rules.
Why is fast warm-up time important?
It helps the system return to full function quickly after power cycles or maintenance.
Can the sensor work in low airflow areas?
Yes. The internal pump ensures stable sampling even in still air.
What signs show the cartridge is aging?
Slight drift or slower response may appear near end of life.
Does humidity affect accuracy?
Readings remain stable within the sensor’s rated humidity range, though extreme changes can affect speed of response.
