美国Apogee SO-110-SS/SO-210-SS/SO-411-SS/SO-421-SS

配有一个热敏电阻温度传感器，用于校正温度变化，

以及一个静态加热器，用于将膜的温度提高到比环境温度高约两度的位置，以防止特氟龙膜上发生冷凝并阻塞传感器的扩散路径

各种气体的影响Sensors are unaffected by CO, CO₂, NO, NO₂, H₂S, H₂, and CH₄. There is a small effect (approximately 1 %) from NH₃, HCI,and C₆H₆ (benzene). Sensors are sensitive to SO₂ (signal responds to SO₂ in a similar fashion to O₂). Sensors can be damaged by O₃
