The portable, handheld VelociCalc Multi-Function Ventilation Meter 9565-A features a menu-driven user interface for easy operation in your local language. On-screen prompts and step-by-step instructions guide the user through instrument setup, operation, and field calibration.
The 9565-A also features an ergonomic, over-molded case design with probe holder and a keypad lockout to prevent tampering during unattended use. The 9565-A model includes the Articulated Probe 966 and is designed for use with a range of plug-in probes.
Measures velocity, temperature, humidity, differential pressure, barometric pressure and has inputs for two K alloy thermocouples. Includes an articulated, telescopic probe and data logging.
VelociCalc Plug-In Probes
The plug-in probes allow users to make various measurements by simply plugging in a different probe that has the features and functions best suited for a particular application. Plug-in probes for the VelociCalc series can be ordered at any time and include a data sheet with certificate of traceability. When it’s time for servicing, only the probe needs to be returned since all the calibration data is stored within the probe.
LogDat2 Downloading Software
The VelociCalc Model 9565 Series includes downloading software called LogDat2. LogDat2 software transfers the stored data from the Model 9565 to a computer as a spreadsheet file. This software is useful for applications such as duct traverses, fume hood, and filter face velocity testing.

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 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. This software is useful for long term, unattended data logging applications such as IAQ and VOC investigations.
