Description Specifications Literature Video Description The TSI VelociCalc® Air Velocity Meter 9545 is capable of measuring velocity, temperature, and relative humidity. The 9545 meter simultaneously measures and logs several ventilation parameters using a telescopic straight probe with multiple sensors including flow and wet bulb and dew point temperature. This air velocity meter is ideal for optimizing HVAC system performance, commissioning, plant maintenance, critical environment certification and duct traverses. The 9545 model is like having multiple meters for the price of one.
