Pump-suction screening breathalyzer with a platinum fuel cell sensor, 0–1.000 mg/L range and a 500,000-record memory.

The AT7300 is built for fast, repeatable alcohol screening before work and at roadside checks. It uses a platinum fuel cell sensor together with an air pump, so the sample is drawn into the cell instead of relying on the subject to blow hard — the reading stays accurate and stable even when the person being tested cannot cooperate fully.

The whole instrument is shaped like a traffic baton, with a 1.44-inch colour LCD, a rechargeable battery charged over USB Type-C and a magnetic back for hands-free placement. An electronic whistle, illumination function and window-breaking tip turn the same unit into a roadside safety tool, while the 500,000-record memory keeps months of screening results on board.

Key Features

1.  Fuel Cell Sensor — a platinum fuel cell element gives high accuracy and reliability, and resists the drift that semiconductor sensors show over time.

2.  Pump Suction Sampling — an integrated air pump draws the breath sample into the sensor, so results do not depend on how hard the subject blows.

3.  Fast Screening — the instrument is ready within 10 seconds of switching on, which keeps queues moving at checkpoints.

4.  Traffic Baton Format — the 396 mm baton body reaches into a vehicle window easily and stays visible during night-time checks.

5.  Traffic Baton Function — built-in baton lighting supports traffic direction while the unit is in use.

6.  Illumination Function — the lamp lights the face of the person being tested for clearer observation.

7.  Magnetic Adsorption and Window Breaking — the magnetic back fixes the unit to the body of a vehicle, and the hardened tip can break a window in an emergency.

8.  Electronic Whistle — produces a loud electronic whistle for stopping vehicles without a separate whistle.

9.  500,000 Test Records — the onboard memory stores up to 500,000 results for later review and export.

10.  USB Type-C Charging — the lithium rechargeable battery charges from a standard USB Type-C cable and runs about 4 hours continuously.

11.  Colour LCD — a 1.44-inch colour display shows the result, unit and battery status in daylight and at night.

12.  Adjustable Blowing Time — sampling time can be set between 1 and 15 seconds to suit screening or evidential-style procedures.
