Product Overview

The SGX series of PS1 and PS4 VOC gas sensors utilize 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 fast response times and are individually calibrated with a test report.

Technical Specifications

Important Notes: All performance is based on conditions at 20C, 50% RH and 1 atm, flow rate>150qcm/min, using SGX recommended circuitry. Sensor performance is temperature dependent; 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.

All specifications outlined are subject to change without notice. SGX Europe Sp. z o.o. 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 to be avoided, both during storage, fitting into instruments and operation. When using sensors on printed circuit boards (PCBs), degreasing agents should be used prior to the sensor being fitted. SGX Europe Sp. z o.o. makes every effort to ensure the reliability of its products. Where life safety is a performance requirement of the product, we recommend that all sensors and instruments using these sensors are checked for response to gas before use.
