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. 8) Poisoning - sensors are designed to operate in a wide range of harsh environments and conditions. However, it is important that exposure to high concentrations of solvent vapours is avoided, both during storage, fitting into instrument and operation. 9) When using sensors on printed circuit boards (PCBs), degreasing agents should be used prior to the sensor being fitted. Warning: By the nature of the technology used, any electrochemical gas sensor offered by SGX Europe Sp. z o.o. can potentially fail to meet specification without warning. SGX Europe Sp. z o.o. makes every effort to ensure the reliability of our products of this type, where life safety is a performance requirement of the product, we recommend that all sensors and instruments using these sensors are checked for response to gas before use. SGX Europe Sp. z o.o reserves the right to make product changes without notice.
