1. Overview
The Oasser T1 is a portable digital breath alcohol tester. It is designed to provide an indication of Blood Alcohol Concentration (BAC) using a semiconductor sensor. The device is compact, battery-powered, and includes multiple disposable mouthpieces.
2. Features
2.1 Sensor & Display
- Semiconductor Sensor: Provides BAC readings.
- LCD Screen: Large, backlit digital display for easy reading.
- Two-Tone Backlight: The screen illuminates in different colours (e.g., red) based on the reading.
2.2 Operation & Alerts
- Single Button Control: One button powers the device on, starts the test, and cycles through units.
- Audible and Visual Alarm: When a BAC reading exceeds 0.08%, the screen illuminates red and a continuous beep sounds.
- Multiple Units: Displays results in three units: %BAC, ‰BAC, and mg/l.
2.3 Physical Design
- Compact Size: Approximately 115mm (L) x 60mm (W) x 20mm (T).
- Replaceable Mouthpieces: Includes four (4) disposable snorkels (mouthpieces).

3. Use Guide
3.1 Before First Use
- Open the battery compartment and insert 3 new AAA alkaline batteries, observing the correct polarity.
- Attach a clean, unused mouthpiece (snorkel) to the device's inlet.
3.2 Taking a Measurement
- Wait: Ensure at least 15 minutes have passed since your last drink. Do not smoke immediately before testing.
- Power On: Press the single button. The device will power on and perform a self-check.
- Blow: When the display indicates ready, take a deep breath and blow steadily and forcefully into the mouthpiece for approximately 5 seconds.
- Read Result: The result will be displayed on the LCD screen within seconds.
- Interpretation:
- If the BAC is above 0.08%, the screen will turn red and a continuous beep will sound.
- You can press the button to cycle the reading between %BAC, ‰BAC, and mg/l units.
- Power Off: The device will automatically power off after approximately 3 minutes of inactivity.
Important Notes for Accurate Testing:
- For maximum accuracy, wait at least 15 minutes after drinking or eating before testing.
- Do not smoke during the test.
- Use a new mouthpiece for each user to ensure hygiene.
- The device requires a recycling time of approximately 25 seconds between tests.
3.3 Changing the Unit of Measurement
After a reading is displayed, press the single button repeatedly to cycle through the available units: %BAC, ‰BAC, and mg/l.
3.4 Replacing the Mouthpiece
Remove the used mouthpiece and discard it. Attach a new, clean mouthpiece from the provided set for the next test.
