Electrochemical Oxygen Sensor O2-A2
The Electrochemical Oxygen Sensor O2-A2 is a sealed‑tube sensor designed for continuous monitoring of oxygen concentration in gases. It delivers a performance output of 80‑120 µA at the standard 20.9 % O₂ level, with a response time (t90) of less than 15 seconds when falling to 0 % O₂. Zero current in pure nitrogen is below 2.5 µA and linearity deviation at 10 % O₂ does not exceed 0.6 %. The sensor maintains output drift under 1 % over three months and retains at least 85 % of its original output for more than 24 months of operation.
The device incorporates a 47‑100 Ω load resistor and is housed in a stainless‑steel body with a diameter of 20 mm and a height of 17.4 mm, weighing less than 16 g. Typical electrochemical O₂ sensors use a platinum catalyst and an electrolyte membrane to generate a current proportional to oxygen partial pressure, a construction shared across the industry. Standard calibration follows a two‑point method using 0 % and 20.9 % O₂ reference gases, which aligns with common practice for laboratory and field installations. The sensor operates reliably between - 30 °C and 55 °C, tolerates pressures from 80 to 120 kPa and functions in non‑condensing humidity up to 99 % RH for short periods.
This sensor is suited for combustion control, indoor air quality monitoring and safety systems where precise O₂ read‑out is required. Buyers such as OEMs of HVAC units, gas‑analysis equipment manufacturers and process plants typically request bulk packaging and sealed glass tubes. Trade terms, incoterms and minimum order quantities are not disclosed in the listing and should be confirmed directly with Week Technology Ltd.

Sourcing Electrochemical Oxygen Sensor O2-A2 from Week Technology Ltd. - China Import Guide
Before placing an order, confirm the sensor’s calibration certificate, the exact load resistor value you intend to use, and whether the units are supplied sealed in glass tubes. Request a sample or a test report that shows performance at your target temperature and pressure conditions. Verify that the supplier can meet any required regulatory approvals for the destination market.
Discuss the preferred Incoterms, such as FOB Shenzhen port or CIF Shanghai, and agree on the packaging format, typically bulk cartons with anti‑static lining. Inquire about the typical lead time for production and shipment, which the supplier has not disclosed, and arrange a freight forwarder familiar with electronic components. Clarify payment terms, for example a 30 % advance letter of credit with the balance upon receipt of inspection documents.
Plan for an incoming inspection that includes visual examination of the sensor housing, verification of the load resistor range, and functional testing of output current at 20.9 % O₂. Request a test report covering zero current in nitrogen and linearity at 10 % O₂. Ensure that the supplier can provide a certificate of conformity or equivalent documentation to support quality assurance.
