TSI’s IAQ-CALC™ Meters are exceptional indoor air quality instruments for investigating and monitoring building air quality. These IAQ instruments simultaneously measure and data log multiple parameters to monitor indoor air quality conditions. The Model TSI-7525 measures CO2, temperature, humidity, and calculates dew point, wet bulb temperature, absolute humidity, humidity ratio and % outside air. The Model 7545 IAQ meter adds CO.
Features & Benefits:
- Easy to use, accurate and reliable
- Take and record measurements for IAQ thermal comfort studies
- Temperature and relative humidity measurements help determine thermal comfort
- Calculates % outside air from either CO2 or temperature
- Directly calculates dew point, wet bulb temperature, absolute humidity and humidity ratio
- Electrochemical sensor measures CO (Model TSI-7545)
- Two-line display shows two parameters simultaneously
- Simultaneously records all parameters and logs up to 14,000 samples with time and date stamp
- TSI LOGDAT™ software permits easy transfer of data to a computer
- Data can be reviewed on-screen, printed or downloaded to
a computer for easy report generation
- Statistics function displays average, maximum and minimum values, and the number of recorded samples
