Drug Testing

We are leaders in the field of alcohol testing using Dräger alcohol breathalyser, evidential alcohol tester and drug testing devices.

For many decades, we have gained knowledge and experience in the fields of breath alcohol and drug testing. We are a world leader in the field of alcohol testing with most police forces in the world using Dräger alcohol breathalyser, evidential alcohol tester and drug testing devices.

For years, Dräger’s alcohol and drugs screening devices have helped police identify lawbreakers, defuse confrontations and bring watertight evidence to court. Our stringent quality controls ensure on-site drug and alcohol testing equipment delivers reliable results.

The vehicle immobiliser helps convicted offenders to control their driving habit. Equally important, our alcohol and drug testing instruments can help to improve the workplace safety of employees and material.
