Operating Temperature:
-40℃~+55℃
Mfr. Part #:
PS4-CO-100
Key Attributes
Model Number:
PS4-CO-100
Product Description
Product Overview
The SGX series of PS1 and PS4 Electrochemical gas sensors utilize a revolutionary 'Solid Polymer Electrolyte' technology based on catalytic reaction. These sensors generate a small current proportional to the target gas concentration, offering a stable, high-quality, and cost-effective manufacturing process. Available in a very small size, they are highly sensitive, do not require power, and exhibit very low cross-sensitivity to other gases. Key applications include TLV monitoring, environmental air monitoring, parking garages, steel industry, oil & petrochemical industry, and leakage detection.

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 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.
- Exposure to high concentrations of solvent vapours should be avoided 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.
- For life safety performance requirements, it is recommended that all sensors and instruments using these sensors are checked for response to gas before use.
