Note: The above cross-sensitivity is not exhaustive. The sensor may respond to other gases. Cross-sensitivity values may vary by production batch and test environment. Calibrate with target gas before use. Calibration with cross-sensitive gases does not guarantee accuracy.

3. Installation Instructions

Ensure correct connection of electrode pins; incorrect connection will affect normal operation.
Avoid contact with organic solvents, paints, oils, and high-concentration gases.
Do not use adhesives directly on or near the sensor to prevent cracking of the plastic housing.
For use in special environments, please contact us in advance.

4. Cautions

Use within the specified range only.
Sensor characteristics must be tested in clean air.
Correct pin connection is mandatory; incorrect pinout will cause functional failure.
Do not apply voltage directly to electrode pins.
Do not break or bend the pins.
Do not subject the sensor to excessive vibration or impact.
Do not use if the sensor housing is damaged or scratched.
Avoid direct contact with organic solvents, paints, chemicals, oils, and high-concentration gases.
Do not solder sensor pins directly; use a matching socket.
Do not disassemble or replace any components.
If storing the sensor after removal from the PCB, short the working electrode and reference electrode pins to reduce initial stabilization time.
For use in non-conventional environments, please contact us.
