modèle 984, 985, 986 et 987 de TSI


Volatile Organic Compounds (VOC)
 Indoor Air Quality Probes

TSI VOC probes are pre-calibrated, plug-and-play accessory probes for multi-purpose meters Models 7575 Q-TRAK monitor and 9565 VELOCICALC meter. When combined with these meters, long-term data analysis can be performed and reported which is useful for monitoring or investigating the indoor environment.

Features and Benefits
  • Pre-calibrated plug-and-play accessory probes for TSI Models
    7575 Q-TRAK™ monitor and 9565 VELOCICALC® meter
    
  • Compact design with ergonomic handle
  • Four versions available with multiple measurement capability
    – Model 984 - Low concentration (ppb) VOC and temperature
    – Model 985 - High concentration (ppm) VOC and temperature
    – Model 986 - Low concentration (ppb) VOC, temperature, CO2 and humidity
    – Model 987 - High concentration (ppm) VOC, temperature, CO2 and humidity
    
  • Calculates VOC exposure in mass concentration
    – Requires knowledge of VOC being measured
    – Enter specific response factor into meter
    
  • Two-year factory warranty
    
  • Send only the probe back for factory calibration

Applications
  • IAQ investigations
  • Industrial hygiene surveys
  • Building commissioning
  • Track down emissions to their source

Data Collection and Reporting
Expanded data logging capacity and the inclusion of TRAKPRO Data Analysis Software provides the capabilities to work more effectively and efficiently.
The Q-TRAK monitor can store up to 38.9 days of data collected at one-minute log intervals. The stored data can be recalled, reviewed on screen, and downloaded for easy reporting. TRAKPRO software helps you to generate professional graphs for your reports.

Field Service
TSI VOC probes are competitively priced to others in the marketplace but feature a lower cost of ownership due its compact design and construction which is geared for field service capability.

Instrumentation
The 7575 Q-TRAK monitor or 9565 VELOCICALC meter feature a menudriven user interface for easy operation. VOC probes are also compatible with AIRFLOW™ Instruments TA460 series and TSI’s discontinued 7565 and 9555 series, if instrument firmware is at revision 2.10 or higher.

On-screen prompts and step-by-step instructions guide the user through operation and field calibration. These instruments also feature an ergonomic, over molded case design and a keypad lockout to prevent tampering during unattended use.

  • Display up to five measurements simultaneously
    
  • Log multiple parameters to investigate trends
  • Calculate dew point, wet bulb and percent outside air (VOC models 986 and 987)
    
  • Store up to 38.9 days of data collected at one-minute log intervals
    
  • User selectable logging intervals and start/stop times
    
  • Internal barometric pressure sensor
    
  • Download data to TRAKPRO™ data analysis software
    – Report generation
    – Graph creation
    – Instrument programming
