The lowest methanol gas reading possible with a point infrared detector is 1.5% LEL or 900 ppm, but a point infrared would not provide information regarding responses below 200 ppm, so a photoacoustic detector with an accuracy of ±10 ppm would be more appropriate if the hazard to be mitigated is occupational exposure to methanol.

Another advantage of gas detector tubes compared with a gas detector is that they are a low-cost measurement without the need for calibration. The disadvantage of gas detector tubes is that the measurement with the tubes is slower and less accurate compared with measurement with a gas detector with a PID sensor or electrochemical sensors.
