Note: This table is for reference only. Calibration
should be carried out with the actual gas at a known
concentration.
This device is designed to be RoHS compliant.

IMPORTANT NOTES
All performance is based on conditions at 20°C,
50% RH and 1 atm, using SGX recommended
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.
