The TSI 9535 VelociCalc Air Velocity Meter measures and completes data logging of ventilation parameters. This meter simultaneously measures air velocity and temperature while calculating flow rate using a straight, telescopic probe equipped with multiple sensors. The VelociCalc 9535 simplifies complex tasks that would require numerous instruments.
