Medical device manufacturing is carried out in controlled environments such as cleanrooms and are highly regulated to ensure that the products are of the highest quality and are completely free of any contamination. Medical devices are categorised in one of two ways: those that are inserted permanently into the body such as pacemakers, stents etc and those that temporarily come into contact with the human body such as needles, bandages and surgical instruments. Cleanrooms for medical device manufacturing must be positively pressurised relative to the access hatches, gowning rooms and airlocks to ensure that the required dust particle count is maintained. Accurate monitoring of these room pressures is required from a GMP perspective and also required by many of the regulatory bodies such as the FDA or medicine board. The Visio-3 is available for flush-mounting with a stainless steel bezel  and can be easily retrofitted into any such cleanroom to give all personnel a visual status of the room pressures. Cleanroom temperature is also critical to ensure a comfortable working environment and can also be critical for some process's.
