Choose Keragon

With Keragon, you’re guaranteed to get an accurate breathalyzer!

We are a specialized company engaged in the import, sale, and maintenance of breathalyzers.

We have the necessary equipment, supplies, and qualified experts to maintain these precision instruments. At Keragon, every breathalyzer is calibrated and tested for accuracy before being delivered to the customer.

The breathalyzer is tested for accuracy during manufacturing, which can be several years before it reaches the end user. Over such a long period, every breathalyzer begins to show some deviations, even when stored properly. This is due to the natural drift in the sensor’s sensitivity over time. For example, with the Draeger Alcotest 4000 model, the drift is 0.4% per month, and this deviation accumulates every month!

Retailers who are not specialists in this field do not have the necessary equipment or expertise, which means they cannot perform precise calibration of the breathalyzers and cannot even test them for accuracy before handing them over to the customer. In short—not a single retailer not specializing in this field checks or calibrates the breathalyzers they sell. This is why breathalyzers purchased from non-specialized companies give incorrect results—even brand-new ones that you’ve just taken out of the box. This renders them unusable, the money spent on them is wasted, and the inaccurate results put you and those around you at risk.

Our experts at Keragon will provide you with a breathalyzer that is proven to work accurately, along with lifetime support.

Breathalyzers require not only initial but also periodic calibration and accuracy checks. This is necessary both because of the sensor’s natural drift and due to the buildup of residues and contaminants from breath during use.

All manufacturers recommend periodic accuracy checks and calibration. The frequency depends on the breathalyzer’s class, manufacturer, series, and model. You cannot obtain this service from non-specialized retailers. Keragon’s experts have the necessary equipment and expertise to test and calibrate your breathalyzer so that you can be confident in its results.

Every breathalyzer offered by Keragon undergoes an initial accuracy and calibration check by our experts and will be serviced not only during the warranty period but also after the warranty expires.
