Breathing Air Testing

Mid-tech provides a worry-free programme for a certified breathing air testing service, carried out by our engineers - the 'competent persons' required by BSEN regulations.

Mid-tech will:

  • test the air quality of your breathing air and provide a certificate of testing.
  • recommend the appropriate correction measures if the air quality fails to meet current legislation.
  • monitor the condition of your air and any degradation will be highlighted.

Future appointments will be scheduled to ensure a continued compliance with legislation, testing even whilst your production continues.
