Usage Notes:
1. Do not contaminate or block the breathable membrane; oil, dust, and organic solvent vapors can permanently damage the sensing film.
2. The sensor is a pre-activated module. Install it as soon as possible after unpacking; store in the original packaging and avoid long-term exposure to air to prevent electrolyte depletion.
3. Replace the entire module when the lifespan ends; do not replace the sensing cell alone.
4. Perform a bump test before each use and calibrate regularly.
