Indoor Air Quality Meters-IAQ-Calc 7545

The IAQ 7545 meter simultaneously measures and records several parameters, including CO, CO 2 , temperature, humidity; and the calculations are dew point, wet bulb temperature, and outside air percentage.

This instrument is useful for monitoring and investigating indoor air quality. The features and benefits you mentioned make it a versatile tool for a variety of applications, including verifying HVAC system performance, optimizing worker productivity by checking IAQ conditions, and complying with regulations and guidelines.

A low-drift NDIR CO2 sensor, along with temperature and relative humidity measurements, helps determine thermal comfort, while an electrochemical sensor measures CO.

In addition, this instrument calculates the dew point and wet bulb temperatures as well as the outside air % of both CO2 and temperature. The ability to display up to three parameters and record up to 26,900 data points with key measured parameters enabled makes it easy to track and analyze data.

The included LogData Download Software with USB cable and NIST calibration certificate add to the convenience of the instrument, making it easy to transfer data to a computer and generate reports.

A rugged carrying case and AC adapter add to the instrument’s portability and versatility. Overall, this seems like a valuable tool for anyone concerned with monitoring and investigating indoor air quality.
