Maintaining air quality standards in the built environment is important for controlling product quality, people productivity & conservation of delicate fabrics or materials in museums, archives or public areas, to eliminate "sick building syndrome".
We supply a comprehensive range of free standing & wall/din rail mounting data loggers, having either single or multi channel sensor inputs for monitoring temperature/humidity/ barometric pressure/CO2, including 21 CFR 11 supported data loggers for pharmaceutical & clinical science laboratory quality control applications.
A quick summary of each instrument is given below, but if you need more comprehensive details, please request a copy of the product data sheet, either by phoning (01767 692692), or send us an email to: info(at)barber-insys.co.uk

The amount of carbon dioxide has been virtually constant at 280 ppm (particles per million) – i.e. 280 gas molecules per million air molecules in the last ten thousand years, however in recent years, this measured value has been increasing rapidly at approx 2 % per year.
A high level of CO2 in the air within a room causes headaches, tiredness & a lack of concentration.
The regulation on CO2 concentration was established in order to evaluate IAQ (Indoor Air Quality).Normal atmospheric air in so-called ‘clean air areas’ has a level of 360 ppm & approx. 500 ppm in urban areas. The limit of 1,000 ppm “Pettenkofer Figure” is still seen as being adequate indoor-air quality.
