The TSI Alnor VelociCalc 9565 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 9565 Series multi-function meters can calculate air flow, heat flow, turbulence, wet bulb and dew point temperature. The TSI Alnor VelociCalc 9565 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 9565 Series multi-function meters include TrakPro and LogDat2 software and the ability to name test IDs.

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 9565 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.
