Carbon Dioxide (CO2) Carbon dioxide is a gas that the human body produces naturally. * Numbers in RED are above the recommended value. Dry cleaners recapture the perchloroethylene during the dry-cleaning process so they can save money by re-using it, and they remove more of the chemical during the pressing and finishing processes. The overall range of mean measured TVOCs levels was 0-3.6 ppm (an equivalent of 0-0.74 ppm 24-hour averaging period concentrations). (reference: Health Canada 1995. CO2: CO2 is a natural compound in the air, with an average outdoor concentration of 300-400 ppm. - operating temperature range of 0°C to +50°C. This will help control other pollutants at acceptable levels. Big Red’s expertise is in identifying and eliminating environment-related reactions or allergies. - Measures CO2 levels in ppm equivalents - CO2 ppm range of 450 to 2000 ppm (parts per million). Indoor levels of air pollutants can be 2-5 times higher, and occasionally 100 times higher, than outdoor levels. Average levels in homes without gas stoves vary from 0.5 to 5 parts per million (ppm). Levels near properly adjusted gas stoves are often 5 to 15 ppm and those near poorly adjusted stoves may be 30 ppm or higher. TVOC. TVOC is the first Intrinsically Safe, fixed photoionisation detector (PID) of its kind for continuous detection and measurement of total volatile organic compounds (VOCs). Paint, paint thinner, adhesives, wall boards, ceiling tiles, and many other materials used to construct buildings all contain VOCs. Green Building Council (USGBC) recommends levels above 1,500 ng/L indicate that IAQ should definitely be improved. Product Details. TVOC 2 is a fixed, continuous VOC gas detector that accurately detects and measures Total Volatile Organic Compounds within industrial working environments. In another study, formaldehyde levels were significantly associated with hospitalization for asthma in children aged six months to three years, again after ruling out confounding from other indoor air pollutants. Formaldehyde is normally present at low levels in buildings, usually below 0.03 ppm both indoors and outdoors. of TVOC concentration. - industrial grade. We are attempting to comply with an indoor air quality standard where we must be able to sense TVOC in the range of at least 65-870 ppb.
