The IAQ320 is intended to let you continuously monitor indoor air quality conditions. It is appropriate for use in commercial buildings, hospitals, schools, manufacturing facilities, and cleanrooms. This meter correctly detects particulate matter, CO₂, IAQ health index, air temperature, and relative humidity to ensure a healthy work environment. With a 10-inch display, visible and audible alerts, and the ability to store up to 12,000 records, the IAQ320 is a straightforward and useful instrument for regulating indoor air quality.

The Air Quality Meter CO260 analyzes indoor air quality for CO and CO2 levels. These gasses, in high quantities, can have an impact on the health and well-being of both humans and pets. CO2 levels should be monitored in schools, office buildings, greenhouses, factories, hotels, hospitals, transit lines, and anywhere else where high volumes of carbon dioxide are generated. In addition to measuring air temperature and relative humidity, the CO260 calculates dew point and wet bulb temperatures. It may manually record up to 99 readings in internal memory or continually record up to 32K values with the accompanying software.
