Output signals from the sensor pins are different. Inappropriate use of the pins in product design will affect the sensor functionality. Exposure to high concentrations of solvent vapors should be avoided under any condition. Mechanical overstress may cause deformation or cracks of the plastic enclosure of the sensor. If the sensor is used in extreme environmental conditions, please contact us for more details.

Cross-sensitivity Data
Gas Concentration (ppm) Output signal (ppm C2H4 equivalent)
Hydrogen Sulfide 50 <1
Sulfur Dioxide 100 <1
Nitric Oxide 10 6
Formaldehyde 10 <1
Ammonia 50 0
Carbon Monoxide 100 <1
Acetylene 10 15

Note: The cross sensitivity are include but not limited to the above gases. It may also respond to other gases.The data in the table above may vary from different batches of sensors and the changes of test environment. Calibration using the gases that have the cross sensitivities to the sensor is not recommended.

Safety Note:

The sensor is designed to be used in certain instruments for life critical applications. To ensure the sensor functioning per its specifications inside the instrument, it is required to read the instrument user's guide carefully and comply with the calibration procedures by using certified target calibration gas before each use. Failure to do so may cause serious injury and fatality. Please do not open the sensor plastic enclosure because the  electrolyte and other chemicals stored inside are harmful.

It is highly recommended for customers to validate the sensor performance using this document as a reference for their product designs or applications.
