SGX Solid Polymer Electrolyte Gas Sensors
The SGX series of PS1 and PS4 Electrochemical gas sensors are using a revolutionary ‘Solid Polymer
Electrolyte’ technology that is based on the principle of catalytic reaction. The target gas to be measured
generates a very small current, proportional to the gas concentration. Our technology oers a stable, high
quality and cost-eective manufacturing process. The SGX solid polymer electrolyte gas sensors are
available in a very small size, are highly sensitive, do not use power and have very low cross sensitivity
from other gases.

Important Notes
• All performance is based on conditions at 20°C,
50% RH and 1 atm, ow rate>150qcm/min,
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.
