The H2‑AF Hydrogen Sensor (H2 Sensor) is an electrochemical detector designed to sense hydrogen concentrations in gas streams. It provides a measurement range up to 2 000 ppm H₂ with a warranty‑limited performance limit at that concentration. Sensitivity is specified as 10 to 25 nA per ppm at a reference point of 400 ppm H₂. The sensor weighs less than 6 g and is supplied as a compact module for industrial integration.
The device operates reliably between - 30 °C and 50 °C and tolerates ambient pressures from 80 to 120 kPa, which matches typical process‑plant conditions. It exhibits a response time (t90) of under 45 seconds to reach 400 ppm, and a resolution better than 0.7 ppm equivalent RMS noise, both standard performance figures for low‑level hydrogen detection. Industry‑standard housing is usually stainless‑steel, a typical material that protects the internal electrolyte from corrosion. Typical power consumption for similar electrochemical sensors is around 20 mA at 5 V, which should be accommodated in most control panels.
These sensors are employed in emissions monitoring, process safety systems, environmental surveillance and volatile organic compound (VOC) detection where hydrogen leakage is a concern. Plant operators, safety equipment distributors and OEMs in the chemical, oil & gas and refinery sectors are the primary buyers. The listing does not disclose MOQ, lead‑time or pricing, so interested parties should confirm those trade details directly with Week Technology Ltd.

Importers should first obtain the sensor’s type‑approval certificates and a datasheet confirming the electrochemical cell composition before ordering. Request a sample unit to verify output linearity, response time and compatibility with your control system. Also confirm that the supplier holds any required export licences for electronic measurement equipment.
Discuss shipping options early; typical Incoterms offered include FOB Shenzhen or CIF Shanghai, and the lead‑time from the Shenzhen manufacturing base should be clarified with the supplier. Payment methods such as irrevocable L/C or T/T are common for electronic components, but confirm the preferred terms and any advance deposit requirements. Because the supplier’s response rate is recorded as 0 %, maintain clear written communication and set firm deadlines for quotation and production schedules.
Arrange a pre‑shipment inspection by an accredited laboratory to test sensor calibration, leakage current and housing integrity. Request test reports for sensitivity, cross‑sensitivity to CO and humidity performance, which are standard quality checks for hydrogen detectors. Ensure that the final export documents include a commercial invoice, packing list, certificate of origin and any applicable CE or RoHS compliance certificates required by your market.
