IAQ-Calc Meters are exceptional instruments for
investigating and monitoring Indoor Air Quality (IAQ). The Model 8732 is a
cost-effective meter for CO2 measurements. To monitor indoor
air quality conditions, the Model 8760 and 8762 simultaneously measure and
data log multiple parameters. The Model 8760 measures CO2,
temperature, humidity, and calculates dew point, wet bulb temperature,
absolute humidity, and % outside air. The Model 8762 adds CO.
Features and Benefits of all models
- Stable, low-drift NDIR CO2 sensor
- Sampling function records multiple point measurements
- Optional portable printer provides hard copy documentation
Additional features and benefits of the model 8760 and 8762
- Temperature and relative humidity measurements are instrumental for determining thermal comfort levels
- Calculates % outside air from either CO2 or temperature readings
- Direct calculation of dew point, wet bulb temperature, and absolute humidity - no psychrometric chart needed
- Electro-chemical CO sensor for measurements made at outdoor air intakes, HVAC systems and parking garages (Model 8762 only)
- 2-line display showing multiple parameters at same time
- Optional detachable secondary temperature sensor
Data logging capabilities of the Model 8760 and 8762
- Data logging ability allows user to log 14,000 samples with a time and date stamp
- Simultaneously records all parameters available
- Continuous data logging for full-cycle monitoring and trend analysis
- Data can be reviewed on-screen, printed or downloaded to a computer for easy report generation
- TSI LOGDAT downloading software permits easy transfer of data to a computer
- LOGDAT Companion Excel Macro automatically graphs your data
- Statistics function displays average, maximum and minimum values, and the number of recorded samples
Applications
- Measure IAQ and comfort conditions in schools, offices and other indoor environments
- Investigate Sick Building Syndrome
- Comply with regulations and guidelines
- Search for built-in-related illnesses
- Verify building HVAC system performance
- Examine building IAQ conditions to optimize worker productivity
