The 7545 IAQ Meter simultaneously measures and data logs multiple parameters, including CO, CO2, temperature, humidity; and calculations are dew point, wet bulb temperature, and percent of outside air.

Thank you for sharing information about TSI’s IAQ-Calc™ Indoor Air Quality Meter 7545. It seems like a useful instrument for monitoring and investigating indoor air quality. The features and benefits you mentioned make it a versatile tool for various applications, including verifying HVAC system performance, optimizing worker productivity by examining IAQ conditions, and complying with regulations and guidelines.

The low-drift NDIR CO2 sensor, along with temperature and relative humidity measurements, helps determine thermal comfort, while the electrochemical sensor measures CO. Additionally, the instrument calculates dew point and wet bulb temperatures and % outside air from either CO2 or temperature. The ability to display up to three parameters and log up to 26,900 data points with key measured parameters enabled makes it easy to track and analyze data.

The included LogDat2 Downloading Software with a USB cable and NIST calibration certificate adds to the convenience of the instrument, allowing for easy transfer of data to a computer and report generation. The hard carrying case and AC adapter add to the portability and versatility of the instrument. Overall, it seems like a valuable tool for anyone concerned with indoor air quality monitoring and investigation.
