Import Co-Ae Carbon Monoxide Sensor Co Sensor — Buy in wholesale FOB from Supplier in China

The CO-AE Carbon Monoxide Sensor is a fuel-cell based detector supplied by Week Technology Ltd. in China. It conforms to the industry-standard 20 mm diameter form factor used in portable gas detectors. The sensor delivers a measurable range up to 10,000 ppm CO with a sensitivity of 10-25 nA per ppm at 2,000 ppm CO. Its response time (t90) is under 50 seconds from zero to 2,000 ppm, and it provides a resolution better than 5 ppm RMS noise equivalent.

Alphasense’s patented electrode technology underpins the long-term stability of the device, exceeding the two-year warranty commonly offered for similar sensors. The unit operates reliably between -30 °C and 50 °C, tolerates pressures from 80 to 120 kPa and humidity levels of 15-90 % RH continuously. Typical fuel-cell CO sensors of this class also require storage in sealed packaging for up to six months at 3-20 °C, matching the conditions stated for this model. A matched 4-20 mA digital transmitter board provides factory-calibrated output, digital zero, and temperature compensation, facilitating integration into monitoring systems.

These sensors are widely used in portable personal safety devices, fixed-point industrial monitors, and building-management ventilation controls. Importers targeting safety equipment manufacturers or environmental monitoring firms will find the specification set compatible with most IEC-61005 compliant systems. Trade terms such as minimum order quantity, incoterms and payment method should be confirmed directly with Week Technology Ltd. before finalising the purchase.

Week Technology Ltd. is an imported-tier supplier based at 16 Floor, Building #3, Zhongke Mansion, Shenzhen, Guangdong, China. The company is classified under the "harbor" trust tier, indicating a moderate level of verification on the platform. Current response metrics show a response rate of 0 % and no recorded average response time, suggesting that communication may require proactive follow-up. The supplier lists the CO-AE Carbon Monoxide Sensor as part of its gas-sensor product line, focusing on devices that employ fuel-cell technology.

No specific certifications, production capacity or MOQ are disclosed in the listing, so buyers must request these details directly. Week Technology Ltd. does not provide public information on year of establishment or client references, limiting third-party validation. The supplier’s profile indicates that it primarily serves international buyers looking for sensor components, but all trade terms remain negotiable per order. Prospective importers should verify the authenticity of calibration certificates and the condition of the matched transmitter board before confirming a purchase.
