Kotex Development Holdings Ltd is a leading alcohol breath tester manufacturer based in Hong Kong since 1988.

We are one of very few manufacturers you could find in the market with competency to manufacture HIGH ACCURACY testers with accuracy specific certifications or approvals worldwide.

We have strong history of supplying to mature market of alcohol testers for example Scandinavia (Sweden, Norway, Finland) for 15 years, North America supplying biggest chain stores for 7 years, and also fast growing market like Eastern Europe and Russia for 6 years. Mature market have high accuracy requirement for alcohol testers where they no longer accept low quality / accuracy of alcohol testers in the market.

Apart from competency in accuracy specific certifications and extensive product quality proven by many years of supplying to high profile retailers in different countries, we are also one of very few manufacturers you could find in the market manufacture ONLY alcohol breath testers (breathalyzers) and nothing else.

In order to help importers especially new importers of alcohol breath testers to understand better on what are the accuracy specific certifications or approvals in the market, we have prepared the following brief introduction:

There are only 3 main certifications or approvals which are accuracy specific (focusing in testing the accuracy of the product) in the market: DOT(US), AS3547(Australia) and NF norm(France). CE / EMC / RoHS / FDA are not accuracy specific certifications. These are important for importers especially new importers of alcohol breath tester who are looking for high quality testers.

DOT certification (US): For North America market, our products accuracy are certified by Department of Transportation (DOT) / National Highway Traffic Safety Administration (NHTSA) as conforming products for alcohol professional screening purposes. DOT certification is the gold standard of accuracy requirement required by high profile importers especially the big retailers in North America and Canada. We have been supplying to US retail for 7th years with our DOT approved models through our US exclusive distributor. Apart from DOT certification which tests on accuracy of our products, our products material and components used (mouthpieces) are also FDA cleared.

In Asia, we are one of only 2 manufacturers in Hong Kong / Mainland officially DOT approved. The other 2 manufacturers with DOT certification are from Korea.

AS3547 certification (Australia): AS3547 standard is another accuracy specific approval for breathalyzer in the market. It is applicable for the Australian market for the high-end consumer market for breathalyzer. AS3547 have a high accuracy requirement where the tolerance of result could not > 0.01% at every point from 0.00% to 0.10% BAC. This involves 10 points of accuracy requirement to test the BAC measuring capability from low concentration to high concentration. Apart for this high requirement of linearity testing, AS3547 also required long term storage testing across time. We are one of the limited suppliers have semiconductor models could be approved - which further proved our gold-engine of semiconductor models, if you are seeking for affordable testers for consumer market.

NF norm (France): NF norm have lower accuracy requirement than AS3547(Australia) as NF norm relatively only focus one point of accuracy at 0.25mg/L. We have wide range of products meeting NF standard.

With our strong client credentials and product-focus history as described above, we are sure we could meet your product expectation, if you are looking for highly accurate alcohol breath tester. For importers who have imported alcohol testers before and now looking for higher accuracy to suit the market trend and customer expectation, please feel free to contact us for distributing opportunity!
