5 Tips for Methanethiol (CH3SH) Gas Sensor
- Avoid exposing the methanethiol sensor to organic solvents, alcohols, oils, high-concentration gases, and corrosive environments, as these can damage the sensing element.
- For accurate calibration of this CH3SH gas sensor, always use standard target gas balanced in clean air. Avoid using interfering gases for calibration due to potential inaccuracies.
- Do not test the gas sensor with non-standard methods, such as exposing it directly to concentrated vapors (e.g., from ammonia water, alcohol, or human breath), as extremely high concentrations can permanently damage it.
- Ensure stable and gentle airflow during calibration or testing of the gas sensor to simulate gas diffusion conditions; unstable or forceful airflow can lead to poor accuracy and repeatability.
- The gas detector sensor pins must be connected via a PCB socket; soldering directly onto the pins or bending them can cause damage.
