Cartridge and device care

If your G7 or cartridge needs to be cleaned, it is important steps are taken to avoid sensor contamination.

Gas sensors are susceptible to contamination by a variety of common chemicals, reducing or eliminating their sensitivity. Care should be taken when using silicones, cleaners, solvents and lubricants in close proximity to 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.

Recommended products and procedures to avoid sensor contamination:

  • Use water based cleaners
  • Use non-alcohol based cleaners
  • Clean the exterior with a soft, damp cloth
  • Do not use soaps, polishes or solvents
