Calibration is the checking and regulation of the precision of a unit by comparing its results with a known value. For example, a known 0.080% alcohol gas content is blown into a breathalyzer, and the unit is adjusted to make sure it reads precisely 0.080 %BAC (blood alcohol content).
Over time the breathalyzer alcohol sensor can lose accuracy. Whether you are working with a professional breathalyser or personal breathalyser, you must have the device calibrated at least every 12 months. Almost all breathalyzer companies offer calibration for a minimal charge, which is typically around $20 (You are generally responsible for the shipping costs to the calibration center.) Your device will usually be recalibrated within a few days after the calibration center receives it.
A warranty is also important on breathalyzer units because, like all products, they can break or malfunction. The more expensive the device you buy, the more important it is to have a warranty. Read the fine print of the warranty to be sure its terms are acceptable and will cover the product under normal use. Misuse can sometimes void a manufacturer’s warranty, making a broken product useless. An extended warranty option is also worth looking into if you plan to purchase a more expensive model.
A breathalyser is a electronic device, and like all electronic devices it should be handled properly. But if the manufacturer’s directions for using, maintaining and calibrating the breathalyser are followed, you should get many years of useful life out of the product.
Breathalyzer tests can save lives if they are done properly on an accurate device. It is essential that you have your breathalyser calibrated and have a warranty available in case of product failure. By doing these two things you can better know that your device is in good working condition and giving you the most accurate reading.
