These Meters are excellent diagnostic instruments for detecting temperature and humidity. |
TSI¡¯s TH-CALC¢â Meters are excellent diagnostic instruments for detecting temperature and humidity. Each hand held instrument measures multiple parameters. The Model 8720 measures temperature, humidity and calculates dewpoint. The Model 8722 adds data logging, and performs wet bulb temperature, absolute humidity and % outside air calculations. These instruments are ideal for conducting thermal comfort studies and Indoor Air Quality (IAQ) evaluations. |
|
Features |
- Direct calculation of dewpoint temperature
- Sampling function records multiple point measurements
- Optional portable printer provides hard copy documentation of your measurements
- View two parameters simultaneously from the large digital display
|
|
Additional Features and Benefits of the Model 8722 |
- Direct calculation of wet bulb temperature and absolute humidity - no psychrometric chart needed
- Automatically calculates % outside air after taking necessary temperature readings
- Optional detachable secondary temperature sensor
|
| |
Data Logging Capabilities of the Model 8722 |
- 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 cyclical monitoring and trend analysis
- Discrete data logging for taking spot measurements
- Data can be reviewed on-screen, printed or downloaded to a computer for easy report generation
- TSI LOGDAT¢â downloading software permits easy transfer of data to a computer
- LOGDAT¢â Companion Excel¢ç Macro automatically graphs your data
- Statistics function displays average, maximum and minimum values, and the number of recorded samples
