Applications
The versatile AZ Portable CO2 CO Temperature Humidity Meter functions as a comprehensive multi-gas detector, proficiently assessing indoor air quality metrics such as CO2 levels, CO concentration, dew point, wet bulb value, and air temperature. This adaptable instrument serves as an invaluable CO2 data logger, ideally suited for diverse environments, including workplaces, offices, hospitals, schools, stations, and residences.
It stands as an indispensable tool for diagnosing indoor air quality (IAQ) issues, particularly relevant due to the adverse effects of poor indoor air quality, including fatigue, reduced concentration, and potential illnesses like sick building syndrome. The significance of monitoring IAQ, particularly CO2 levels and air ventilation, is widely acknowledged in various settings such as offices, classrooms, factories, hospitals, and commercial establishments, aligning with regulations related to industrial hygiene in specific regions.
Of notable concern is the highly hazardous nature of CO, an odorless, colorless, and tasteless gas that is perilous to both humans and animals. Keeping CO concentration within safe limits is pivotal, with ASHRAE Residential standards 62-1989 underscoring a maximum indoor air quality threshold of under 9 ppm for living areas. Furthermore, adherence to the OSHA exposure limit, necessitating the removal of employees from enclosed spaces if CO concentration surpasses 100 ppm, is imperative.
Employing advanced NDIR (non-dispersive infrared) technology, the portable AZ Combo CO2, CO, Temperature RH Meter guarantees reliability and long-term stability. Its capabilities extend to assessing HVAC system performance and air ventilation control, making it a valuable asset. Crafted by AZ Instrument, a reputable IAQ CO2 Meter manufacturer, the AZ 77597 CO and Carbon Dioxide Detector reflects the company's extensive expertise in creating such instruments.
