IMPORTANT NOTES
All performance is based on conditions at 20°C,

circuitry.
Sensor performance is temperature dependant;
please contact SGX for temperature performance
other than 20°C.
Do not solder to the connector pins as this may
damage the sensor and thereby invalidate the
warranty.
Details on recommended connector pins can be
found in the Frequently Asked Questions within
the Gas Sensor section of the SGX website.
This device is designed to be RoHS compliant.

Note: This table is for reference only and are typical values. 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.
