Gas sensors are susceptible to contamination by a variety of common chemicals, reducing or eliminating their sensitivity.

Take care when using silicones, cleaners, solvents, and lubricants near sensors as exposure may cause permanent damage to the sensor. If a device is exposed to a new chemical or compound, it is best practice to bump test and calibrate units to ensure proper sensor function is maintained.
