The ETO-B1 Ethylene Oxide Sensor is an electrochemical gas detector with platinum electrodes and a liquid electrolyte enclosed by a gas-permeable membrane. It is designed to measure ethylene oxide concentrations in industrial sterilization and medical environments, with a performance range up to 100 ppm and a sensitivity of 2000 to 3200 nA/ppm at 20 ppm EtO. The sensor responds to 90% of a 20 ppm concentration within 200 seconds and maintains resolution below 0.1 ppm RMS noise.
The sensor operates within a temperature range of -30°C to 50°C and humidity levels of 15% to 90% RH continuously. It is rated for atmospheric pressure between 80 and 120 kPa and weighs less than 13 grams. These specifications align with standard requirements for toxic gas sensors used in enclosed sterilization chambers and emissions monitoring systems. The sensor is typically paired with a matched transmitter board that provides 4-20mA and digital outputs with factory calibration and temperature compensation.
This sensor is purchased by medical device manufacturers, laboratory equipment distributors, and environmental compliance firms operating in regulated industries. Buyers typically require it for continuous monitoring systems that enforce OSHA or EU workplace exposure limits. The sensor is sold as a component, not a complete system, and is often integrated into custom gas detection units. Trade terms are typically FOB Shenzhen, with minimum order quantities determined by integration volume and application 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 supplier with harbor trust tier, indicating verified export compliance and logistics capability. The listing does not state its founding year, workforce size, or manufacturing capacity, nor does it claim certifications or client names.
The company functions as a distributor or integrator of Alphasense sensor components, sourcing the ETO-B1 for resale. There is no indication of in-house sensor production. Its primary role appears to be fulfillment and export coordination, supported by a physical presence in Shenzhen's electronics export corridor. Buyers should confirm direct sourcing relationships with Alphasense if technical documentation or traceability is required.
The ETO-B1 is a specialized electrochemical sensor designed for detecting ethylene oxide (ETO) gas in industrial and medical sterilization environments. Alphasense manufactures these toxic gas sensors for emissions monitoring and workplace safety applications. They are widely imported by laboratory equipment distributors, medical device manufacturers, and environmental monitoring firms, with demand driven by strict EHS regulations governing ethylene oxide exposure limits.

Before ordering, verify the sensor's calibration certificate, batch number, and compatibility with your transmitter board. Confirm the membrane integrity and absence of moisture damage in the packaging. Request the Alphasense datasheet and application note AAN113 to validate performance claims. Do not accept sensors without a visible date code or manufacturer imprint.
Confirm lead time with the supplier, as sensors are often shipped from Shenzhen via air freight. Standard Incoterms are FOB Shenzhen. Payment terms are typically 30% advance, 70% against copy of bill of lading. Ensure packaging includes anti-static and humidity-controlled materials. Request tracking and customs documentation in advance.
Inspect sensors for physical damage, moisture ingress, or broken seals upon arrival. Test sensitivity using a known 20 ppm ethylene oxide source and record output in nA/ppm. Verify the output signal matches the transmitter's input range. Retain sample units for reference in case of field performance issues. Request a certificate of conformity with each shipment.
