Description
TSI 9545-A VelociCalc Air Velocity Meter for Humidity, Temperature, and Velocity with Calculation and Data Logging, Articulating Telescopic Probe
Measures humidity/velocity/temp, calculates flow/wet bulb/dew point, data logging
The VelociCalc 9545 meter simultaneously measures and data logs several ventilation parameters using a single probe with multiple sensors. Ideal for optimizing HVAC system performance, commissioning, plant maintenance, critical environment certification and duct traverses. Includes the articulated probe.
