Measurement Parameters

On-screen prompts and step-by-step instructions guide you through instrument setup, operation, and calibration. The TSI 9565 VelociCalc 9565 measures the important parameters of: 

• Velocity
• Temperature
• Humidity
• Differential pressure; and
• Barometric pressure.

Key Features and Benefits of the TSI 9565

The TSI 9565 features a menu-driven user interface for effortless operations, and the device combines a host of attributes tailored to the specific needs of HVAC professionals:

• Large LCD: As a productivity enhancer, the extra-large graphic screen displays up to five measurements simultaneously while providing measurement guidance via on-screen messages and instructions.
• Intuitive: The menu-driven interface makes for an effortless setup and ease of use – saving you time and money.
• Accurate: Extremely precise, best in class air velocity accuracy (±3% of reading or ±0.015 m/s (whichever is greater) – so you trust your data.
• Sensor: The included air velocity probe measures air velocity, temperature and relative humidity in one component – simple!
• Inclusions: A differential air pressure sensor for more comprehensive measurements.
• Surface Temperature Measurement: Another critical measurement for many investigative HVAC tasks. The TSI 9565 accommodates two K-alloy thermocouples.
• Datalogging: For enhanced versatility, the TSI 9565 offers HVAC professionals several user-adjustable data logging formats.
• Data Storage: The TSI 9565 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.
• Included Software: The TSI 9565 includes downloading software called LogDat2. The program transfers stored data from the ventilation meter to a computer as a spreadsheet file. This feature is helpful for applications such as testing duct traverses, fume hoods, and filter faces.
• Ergonomic Design: The unit features an over-moulded design with a handy probe holder and a keypad lockout to prevent tampering during unattended use.
• Expandable: For increased functionality, there are several intelligent plugin probes available (sold separately) include:
  • TSI 980 CO2, Temperature and Humidity Probe
  • TSI 982 CO2, CO, Temperature and Humidity Probe
  • TSI 984 VOC (ppb) and Temperature Probe
  • TSI 985 VOC (ppm) and Temperature Probe
  • TSI 986 Low Concentration VOC (ppb), Temperature, CO2 and Humidity Probe
  • TSI 987 Low Concentration VOC (ppm), Temperature, CO2 and Humidity Probe
