The TSI Alnor VelociCalc 9555 Series multi-function ventilation meters are portable, handheld instruments available with
or without a differential pressure sensor. Generally used for a wide array of applications-- HVAC, clean room
certification, ventilation evaluations, thermal comfort studes, IAQ investigations and process air flow testing--
the TSI Alnor VelociCalc is designed to work with a wide range of plug-in probes.
With probes designed to measure air velocity, temperature, humidity, CO and CO2, the TSI Alnor
VelociCalc 9555 Series multi-function meters can calculate air flow, heat flow, turbulence, wet bulb and dew
point temperature. The TSI Alnor VelociCalc 9555 Series features a large graphic display which can
simultaneously display up to 5 measurements. Up to 26,500+ samples and 100 test IDs can be logged, either manually
or continuously, into the internal memory. Other features of the TSI Alnor VelociCalc 9555 Series multi-function
meters include TrakPro and LogDat2 software, the ability to name test IDs, and Bluetooth printer capabilities.
TrakPro data analysis software is a Windows-based software program that works with a variety of TSI data logging
instruments, including the TSI Alnor VelociCalc 9555 Series. This unique software helps you pre-program instruments,
store and organize your test data, and generate detailed graphs and reports needed to effectively communicate results.
The LogDat2 software transfers stored data to a computer spreadsheet program. It is necessary for downloading data
from the TSI Alnor VelociCalc meters.
All TSI Alnor VelociCalc 9555 Series multi-function meters ship with the instrument, hard carrying case, 4
alkaline batteries, USB cable, LogDat2 and TrakPro downloading software, operation and service manual and
calibration certificate. Additionally, the 9555, 9555-A and 9555-P models include an 8-foot (2.4 meter)
rubber tube and one static pressure tip.
