The VelociCalc® Air Velocity Meter 9545-A is like having multiple meters built into one. This meter simultaneously measures and data logs several ventilation parameters using a single probe with multiple sensors. It measures velocity, temperature and relative humidity; and calculates flow, wet bulb and dew point temperature. Ideal for optimizing HVAC system performance, commissioning, plant maintenance, critical environment certification and duct traverses. Features
Extended air velocity measurement range of 0 to 6000 ft/min
User adjustable, variable time constant modes allow a steady display when measuring fluctuating air flow
Perform multiple point averaging, minimum and maximum measurements
Measures %RH and calculates Dew Point and Wet Bulb temperatures, no psychometric chart needed
Calculates volumetric flow, and actual/standard velocity
Data log 12,700+ samples and 100 test IDs
Auto-Save Logging Function
LogDat2â„¢ downloading software included
Telescopic probe has etched ruler down the side making duct transverse measurements much easier
Volume flow rate is calculated and displayed in ft3/min, l/s or m3/hr with input of duct size & shape
Articulating tip probe can bend up to 90°for convenient measurement of fume hood and BSC face velocity and HEPA filter face velocity
