Import As510 Remote Air Quality Monitor — Buy in wholesale FOB from Supplier in China

The AS510 Remote Air Quality Monitor from Week Technology Ltd. is a multi-parameter environmental sensing station centred on a 32-bit floating-point ARM microcontroller. It integrates four Alphasense A4 electrochemical cells for carbon monoxide, nitrogen monoxide, nitrogen dioxide, and ozone detection down to parts-per-billion levels, supplemented by an optional sulphur dioxide cell. An NDIR CO2 sensor (Atmospheric Sensors/Alphasense or SenseAir variant), a laser optical particle counter for PM1, PM2.5 and PM10, and a photoionisation detector for volatile organic compounds complete the gas and particulate suite. Temperature, relative humidity, GPS positioning, and an optional microphone for ambient noise characterisation are also included, with all data logged locally to 16GB SD card and transmitted via GPRS every 15 minutes.

The sensor architecture reflects a design for regulatory-grade outdoor monitoring and indoor industrial hygiene applications. Electrochemical cells offer cross-sensitivity profiles that vary with temperature and humidity, so the integrated T/RH sensor supports compensation algorithms in the ARM firmware. The laser particle counter uses optical scattering to size particles into three aerodynamic fractions, while the NDIR CO2 sensor measures infrared absorption at 4.26 micrometres. Data sampling at high frequency with 20-second averaging smooths transient spikes, and store-and-forward buffering maintains data integrity during GPRS outages. The unit requires a data-capable SIM card for cellular backhaul, which can be provisioned by Atmospheric Sensors or an alternative carrier.

Primary buyers include environmental consultancies, municipal air quality networks, and industrial facilities managing emissions compliance. The AS510 suits fixed outdoor installations with a Stevenson screen or equivalent weather shield, or indoor wall-mounted deployments using the supplied brackets. Mains power with a waterproof connector is standard; buyers should confirm input voltage range, surge protection, and whether battery or solar backup options exist. The 16GB SD card stores extended results as a redundant archive for later recovery or audit trail purposes.

Week Technology Ltd. is headquartered at 16 Floor, Building 3, Zhongke Mansion, Shenzhen 518067, Guangdong province, China. The supplier holds a harbour trust tier and an imported supplier tier, with a recorded response rate of 0.00 percent and zero average response hours. The address places the company in Nanshan district, within Shenzhen's core technology corridor near the University Town and high-tech industrial parks.

The company name and product line indicate a focus on environmental and measurement technology, though the source provides no founding year, employee count, revenue, factory ownership status, or client references. Buyers should request a business registration certificate, VAT invoice sample, and any ISO 14001 or ISO 9001 certifications claimed. Given the zero response metric, initial contact should include a clear technical enquiry to gauge engineering support depth, as the AS510 integrates third-party sensors requiring calibration and cross-sensitivity management expertise.
