Import Hcl-A1 Hydrogen Chloride Sensor (Hcl Sensor) — Buy in wholesale FOB from Supplier in China

The HCL‑A1 is an electrochemical sensor designed to detect hydrogen chloride (HCl) and, additionally, hydrogen bromide (HBr) in gaseous environments. Its measurement range extends up to 100 ppm of HCl, with a sensitivity of 80 - 130 nA per ppm at the 25 ppm reference point. The sensor achieves a response time (t90) of less than 300 seconds from zero to 25 ppm and delivers a resolution better than 1 ppm equivalent RMS noise. Operating specifications include a temperature window of - 30 °C to +50 °C, a pressure range of 80 - 120 kPa, and a relative humidity tolerance of 15 % to 90 % continuous.

Electrochemical HCl sensors are typically zero‑biased, which simplifies power requirements and circuit design, a feature noted for the HCL‑A1. Standard industry practice calls for periodic calibration every six months and a useful lifespan of around two years under normal operating conditions. Typical power consumption for such sensors is 3 - 5 V at a few milliamps, compatible with most process‑control hardware. The device weighs less than 6 g, allowing compact installation in portable or fixed monitoring stations.

The sensor is suited for emissions monitoring, process safety, environmental compliance and volatile organic compound (VOC) detection in chemical plants, refineries and waste‑treatment facilities. Buyers usually arrange procurement through standard trade terms such as FOB or CIF, with payment by L/C or T/T, and should verify the minimum order quantity with the supplier. As the supplier provides the sensor from Shenzhen, China, confirming lead times and shipping details before order finalisation is recommended.

Week Technology Ltd. is situated on the 16th floor of Building #3, Zhongke Mansion, Shenzhen, Guangdong, China. The company is classified as an imported‑tier supplier with a harbour trust tier, indicating it satisfies the platform’s basic verification criteria. Its profile records a response rate of 0 % and no average response time, suggesting that buyers may need to initiate contact proactively. The firm specialises in the development and export of electrochemical gas sensors for industrial and environmental applications.

The listing does not provide details on the company’s founding year, production capacity or client references, so those should be obtained directly from the supplier. No additional certifications beyond the product description are mentioned for the supplier itself. Prospective purchasers are encouraged to request the supplier’s quality management system documentation, calibration certificates and any relevant regulatory approvals before finalising a purchase.
