In New Zealand, law enforcement upholds a maximum allowable Blood Alcohol Concentration (BAC) limit of 0.05% (250 mcg/L). For restricted licenses, which often apply to younger drivers or those with prior penalties, a BAC of 0.00% is generally required.
The accuracy of a breathalyzer is influenced by the quality of its internal sensor and its overall design.
The fuel-cell sensor units offered by Breathalyzers New Zealand are exceptionally precise, with capability to measure to the thousandth decimal place.
It is essential to operate breathalyzers properly and to recalibrate them in accordance with the specific servicing needs of each model.
Before taking the test, it is crucial to wait 15–20 minutes after your last consumption of alcohol, food, or other liquids before using your breathalyzer. For personal use devices, please allow a 3-minute gap between consecutive tests to allow the sensor to reset.
Avoid using hand sanitiser or any alcohol-based cleaning products near the testing area. Conducting tests outdoors can help reduce the risk of ambient readings. Make sure the mouthpiece is firmly attached, take a deep breath, and most importantly, blow steadily until you hear a click. Failing to blow consistently will result in an error, as the device will not receive a complete sample.
Fuel-cell models typically offer 5 years+ of service if they are maintained within calibration and if the care guidelines are adhered to. However, as technology progresses, it is likely that a new device will need to be acquired.
