Micro Direct relies upon the proven track record of stability and reliability of the Micro Medical spirometers. They have been tested in some of the harshest environments on earth and are manufactured to ISO9002 quality guidelines. Three generations of ATS testing machines are used to ensure the continuing quality of our products.

Here are just a couple of examples of where spirometers available from Micro Direct have been independently tested and used.

This expedition had seventy five members with some coming from as far afield as New Zealand and America with two members actually climbing to the summit.  None of the members had ventured above 7,500m before. The objectives of the expedition were to perform 16 medical research projects, 2 environmental projects, conduct an educational campaign and promote the work of a Nepal based charity. One of the research projects was entitled 'Changes in Spirometry at Altitude'. The Micro Medical Micro Spirometer proved ideal for this as the turbine technology means the results are not affected by either climate or altitude, unlike some spirometers using different technologies.
