Do not solder to the connector pins as this may damage the sensor and thereby invalidate the warranty. 2.) Details on recommended connector pins can be found in the Frequently Asked Questions within the Gas Sensor section of the SGX website. 3.) All performance specifications are based upon the following environmental conditions: 20C, 50% relative humidity, 101kPa. 4.) Cross Sensitivity Data is for information only. Calibration is recommended with target gas as the accuracy of calibration and measurement cannot be ensured. 5.) The cross sensitivities are including but not limited to the gases stated in the table. It may respond to other gases. 6.) The cross sensitivities may fluctuate between 30% and may differ from batch to batch or across sensors life time. 7.) The device is designed to be RoHS compliant.
