Blackline cartridges support a variety of sensor types, including MPS, IR, electrochemical, and PID. While some are highly resistant to contamination or drift, all sensors can degrade over time when exposed to harsh conditions or chemical vapors.

• MPS sensors are factory calibrated and resistant to poisoning. They maintain accuracy across a wide range of combustible gases without requiring field calibration.
• IR sensors are also resistant to poisoning but may experience baseline drift in environments with high humidity or rapid temperature shifts.
• Electrochemical sensors are more susceptible to poisoning and drift. Exposure to vapors from silicons, solvents, lubricants, or industrial chemicals may permanently affect performance.
• PID sensors are sensitive to high concentrations of VOCs. Contaminated lamps or sensor overloads can reduce accuracy and may require cartridge replacement.

Avoid exposure to chemical vapors such as silicons, solvents, and lubricants, which may interfere with sensor performance across all sensor types.
