Import Eto-A1 Electrochemical Ethylene Oxide Sensor — Buy in wholesale FOB from Supplier in China

The Eto-a1 Electrochemical Ethylene Oxide Sensor is a precision gas detection device designed for continuous monitoring of ethylene oxide (C2H4O) in industrial and environmental settings. It operates within a 100 ppm performance limit, with a sensitivity range of 2000 to 3200 nA/ppm when exposed to 20 ppm of ethylene oxide. The sensor responds to gas concentrations with a t90 time under 150 seconds and maintains a resolution better than 0.1 ppm equivalent under RMS noise conditions. It is compatible with Alphasense's toxic evaluation board for bias voltage tuning to match application-specific needs.

This sensor uses an electrochemical cell with a solid electrolyte and platinum electrodes, typical for industrial toxic gas sensors in this class. It is available in A and B series variants, differing in calibration stability and long-term drift characteristics. The operating environment supports temperatures from -30°C to 50°C, pressures between 80 and 120 kPa, and humidity levels from 15% to 90% RH continuously. The unit weighs less than 6 grams and is designed for integration into fixed or portable gas detection systems without requiring external amplification circuitry.

Buyers include manufacturers of medical sterilization equipment, chemical processing plants, and environmental monitoring firms requiring compliance with occupational exposure limits. The sensor is typically integrated into multi-gas detectors, process safety systems, or emissions monitoring stations. Packaging is bulk or tray-based for OEM integration. Trade terms are FOB Shenzhen, with minimum order quantities confirmed directly with the supplier. Lead times vary based on batch size and calibration requirements.

Week Technology Ltd. is a supplier based in Shenzhen, Guangdong, with a registered address at 16 Floor, Building #3, Zhongke Mansion. The company is listed as an imported tier supplier with harbor trust verification, indicating a history of verified export transactions. The listing does not specify years in business, production capacity, or client names. Response rate and average response time are not available, suggesting limited buyer interaction on the platform.

The company specializes in sourcing and distributing electrochemical gas sensors, primarily for industrial safety and environmental monitoring applications. It does not manufacture the Eto-a1 sensor itself but acts as a distributor of Alphasense-branded components. No certifications, quality management systems, or R&D capabilities are stated in the listing. Buyers should request documentation for traceability and calibration certificates before ordering.
