Serial number• Under no circumstances should the sensor be disassembled, nor should the sensor can and/or cap bedeformed.
• Sensor characteristics may be significantly changed when the sensor is contaminated by alkaline
metals, especially salt water spray.
• Sensor characteristics may be irreversibly changed by the exposure to high concentrations of basic
gases such as ammonia.
• At temperatures higher than the operating temperature, the sensing membrane may deteriorate,
resulting in irreversible change of sensor characteristics.
• Sensor characteristics may be changed due to soaking or splashing the sensor with water.

CautionInstallation site should be examined, giving careful consideration to the following conditions.
Please note that this product is designed for indoor use only.
[This instrument is intended to be used under the following environmental conditions.]• Free air flow
• No exposure to direct sunlight, an ambient temperature of -10 to 50 (14 to 122 ) that does notchange rapidly, and no icing• An ambient non-condensing humidity of 10 to 95 %RH• Avoid exposure of sensor where silicone adhesives, hair grooming materials, or silicone rubber/putty
may be present. Silicone vapors may cause clogging of the gas diffusion route.
• If severe dew condensation occurs for a long period inside of the sensor or on the sensor surface, it may
cause clogging of gas diffusion route or deterioration of the sensing membrane. Mild dew condensation
which occurs in normal indoor air would not cause any significant damage.
• If the sensor is exposed to hydrogen sulfide or sulfuric acid gas, sensor components such as the gas
diffusion film, can, and cap may be corroded, resulting in the sensor damage.
• Vibration and shock may cause an open or short circuit inside the sensor.
• Extremely high concentrations of dust or oil mist may cause clogging of the sensor's internal structure.
• If the sensor is exposed to organic vapors such as alcohols, acetone, or volatile oils, these gases may
adsorb on the sensor surface, resulting in temporary sensor drift.

Maintenance• Be sure to conduct periodic inspection once a year (once every six months in a highly CO concentratedplace).
• Change the sensor if the measured value does not drop below 30 ppm in air (fresh air).
Also change the sensor when no output occurs.
