SGX Solid Polymer Electrolyte Gas Sensors - VOC

Product Overview

The SGX series of PS1 and PS4 Electrochemical gas sensors leverage a revolutionary 'Solid Polymer Electrolyte' technology based on catalytic reaction principles. These sensors generate a small current proportional to the target gas concentration, offering a stable, high-quality, and cost-effective manufacturing process. They are characterized by their very small size, high sensitivity, zero power consumption, and low cross-sensitivity to other gases. Ideal for general gas detection, consumer markets, VOC gas detection, mobile phone noses, and indoor/outdoor air quality monitoring, these sensors provide reliable performance in various applications.

• Sensor performance is temperature dependant; please contact SGX for temperature performance other than 20C.
• 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.

Cross Sensitivity

Note: 1) The above interference factors may vary due to different sensors and service life, please refer to the actual test results. 2) This table is not complete for all cross gases, other gas please contact with us.
