Breathalyser sales and distribution. We sell breathalysers (alcohol testers) and we have a range that includes personal, business and industry units. Breathalysers can be used in the work place to test staff on the shift. It is not safe for employees to operate machines and vehicles whilst under the influence of alcohol. If you use your own breathalyser you can test yourself before you drive if you have been out dining and drinking with friends. Don't Drink and Drive. Arrive Alive and stay Alive. Breathalysers save time, money and lives.
