TSI Alnor VOC Specifications

VOLATILE ORGANIC

COMPOUNDS (VOC)

INDOOR AIR QUALITY PROBES MODELS 984, 985, 986 & 987

TSI VOC probes are pre-calibrated, plug-and-play accessory probes for multi-purpose meters including, Q-Trak™ Monitor 7575, VelociCalc® meter 9565 and Airow™ Instruments TA465 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.

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 eectively

and eciently. 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.

Probe Dimensions

Length 7.0 in. (17.8 cm) (excluding handle) Base Diameter 0.75 in. (1.9 cm) Tip Diameter 1.0 in. (2.54 cm)

Note: The 984 and 986 probes are designed to measure ppb concentrations of VOCs. The 10 to 20,000 ppb range corresponds to 0.01 to 20 ppm.

Accuracy with instrument case at 77°F (25°C), add uncertainty of 0.05°F/°F (0.05°C/°C)

for change in instrument temperature.

Accuracy with probe at 77°F (25°C). Add uncertainty of ±0.2%/°F (±0.36%/°C)

away from calibrated temperature

Accuracy with probe at 77°F (25°C). Add uncertainty of 0.1% RH/°F (0.2% RH/°C)
