Import Alcohol Tester — Buy in Bulk from Supplier in China

The Hualixin AT-818 is a handheld breathalyser built around a high-precision semiconductor sensor, designed for workplace and commercial alcohol screening. Its detection range spans 0.000-0.199% BAC, 0.00-1.990 g/L BAC, and 0.000-0.995 mg/L BrAC, with a calibrated alarm threshold triggered at 0.050% BAC (0.500 g/L BAC, 0.250 mg/L BrAC). Accuracy is specified at ±0.01% BAC at the 0.05% BAC calibration point, and results display on a blue-backlit 3-digit LCD screen. The unit is manufactured in Shenzhen, Guangdong Province, and ships from Hualixin's facility at 4/F, East Block 2, Dongfangming.

The semiconductor sensor at the core of the AT-818 operates on the standard principle of alcohol oxidation, where ethanol vapour alters electrical resistance across a tin-oxide substrate. Response time is rapid, though the supplier does not publish the exact seconds-to-result figure. Semiconductor sensors of this class typically require recalibration every 6-12 months under regular use, and performance can drift in extreme temperatures or high humidity. The blue backlight LCD ensures readability in low-light environments such as night-shift checkpoints or dimly lit venue entrances.

Buyers commonly deploy this model in corporate fleet management, hospitality venue entry points, and construction-site safety programmes where cost-effective screening outweighs the need for evidential-grade measurement. The compact form factor suits both fixed-point and mobile use. Given the zero-percent response rate and harbour trust tier, importers should treat initial contact as exploratory and request current stock status, sensor calibration certificates, and warranty terms before committing to volume orders.

Hualixin operates from 4/F, East Block 2, Dongfangming in Shenzhen, China, within the dense electronics manufacturing corridor of Guangdong Province. The supplier is classified as an imported-tier account with harbour trust tier, indicating basic marketplace verification without additional assurance layers. The response rate is published at 0.00% with zero average response hours, which signals that direct communication may be delayed or inconsistent. Importers should not rely on rapid quotation turnaround from this profile.

The listing provides no information about manufacturing certifications (ISO, CE, or domestic Chinese standards such as GB/T), company founding year, employee count, or export history. What is known is limited to the product model and sensor specifications. Buyers are advised to request factory audit reports, quality management system documentation, and sample performance data before placing bulk orders. The absence of response data makes video verification or third-party inspection particularly important for this supplier.
