NIFRS need an accurate measurement of cardiovascular fitness to ensure personnel are at the required fitness to be an  Operational Firefighter. COVOX testing in our Service is a very accurate way of assessing aerobic fitness and how it can be improved if necessary. May I thank you for your continued technical support and guidance. Damien Cassidy Physical Training Advisor Northern Ireland Fire and Rescue Service. November 2020

In the period of approximately two years since installation, COVOX has provided excellence in reliability in measurements and ease of operation. This gas analysis system has been used in approximately 7,000 exercise test analyses. It has successfully formed part of the integrated approach to teaching, research and consultancy. Ian Swaine, DEMontford University

I thought you would be interested in the present position with regard to the practical use of the COVOX Microlab in respect to non-research work within the Constabulary. All officers eligible for promotion are required to undergo a fitness assessment in order to achieve the desired level of cardiovascular performance before taking up a new post. May I take this opportunity, yet again to thank you for supplying such a suitable medium for such a demanding schedule of assessments.

David Clarke, Force Physical Education Officer, Devon and Cornwall Constabulary

I would like to thank you on behalf of West Mercia Constabulary and the NSPCC Marathon Team for the personable and professional way you conducted yourself, and the quality of the information you delivered to the group. We were all very impress by the technology (COVOX Analyser). It has given us food for thought for the future. I am sure it will go a long way to ensuring that we achieve the right result in the marathon. David Thursfield, Deputy Chief Constable, West Mercia Constabulary

I have found the COVOX to be robust, reliable and user-friendly and I can strongly recommend it for use in student laboratory work. Dr Neil Armstrong, Reader in Exercise Science, Director, P.E.A. Research Centre, University of Exeter

I have been using the COVOX Gas Analysis System since 1988 in Leisure Centres in Teignmouth and Torbay. It provides an accurate measurement of oxygen consumption, which is reliable and repeatable. I have been very satisfied with the apparatus and with the results that it provides.

Dr P.R. Travers, M.B.,B.S., D.Phys. Med

I am pleased to report many years of excellent performance from our COVOX System. We have only two problems at the moment : 1) Can you send us a replacement dryrite container. A student dropped the original. 2) The software occasionally crashes, usually at the point of printing out the results, I think because the datafiles are almost full. How do we fix this problem? I would be interested in your comments on the longevity of our COVOX and if you think upgrades are possible. Please send a current brochure.  Dr Martin Farrally, St Andrews University.
