The TSI 9545 VelociCalc Air Velocity Meter simultaneously measures and data logs several ventilation parameters using a single probe with multiple sensors.

It measure velocity, temperature and calculate flow. The Model 9545 also measures relative humidity, and calculates dew point, and wet bulb temperature.

The product has telescopic straight probes.
