TSI IAQ-Calc™ Indoor Air Quality Meter 7545 is an outstanding instrument for investigating and monitoring indoor air quality or IAQ. Handheld, easy to use allowing you to gather your data and work with ease. Model 7545 adds detection of carbon
monoxide (CO).
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.
The proprietary TSI LogDat2™ Downloading Software permits easy transfer of data to a computer. Data can be reviewed on-screen, or downloaded to a computer for easy report generation. Statistics function displays average, maximum and minimum values, and the number of recorded samples.
