Temperature 6 months in original Sensor performance is temperature dependant Storage Life Packaging (0 to 20C) please contact SGX for temperature performance other than 20C. Expected Operating Life > 24 months in air Do not solder to the connector pins as this may damage the sensor and thereby invalidate the INTRINSIC SAFETY DATA warranty. Maximum at 2000 ppm 0.3 mA Details on recommended connector pins can be found in the Frequently Asked Questions within Maximum o/c Voltage 1.3 V the Gas Sensor section of the SGX website.

Cross Sensitivities may not be linear and should not be scaled. Calibration should be carried out with the actual gas at a known concentration. TEMPERATURE POISONING SGX 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. When using sensors on printed circuit boards (PCBs), degreasing agents should be used prior to the sensor being fitted.
