Features & Applications

The VelociCalc Air Velocity/Temperature Meter is like having multiple meters for the price of just one. This meter simultaneously measures and data logs several ventilation parameters using a single probe with multiple sensors. It measures velocity, temperature and calculates flow.

Features:

• NIST Certificate of Calibration
• Simple to operate
• Accurate air velocity measurement
• Simultaneously measure temperature and velocity
• Displays up to three measurements simultaneously
• Calculates volumetric flow, and actual/standard velocity
• Data log 12,700+ samples and 100 test IDs
• LogDat2 downloading software included
• Includes a telescopic straight probe

Applications:

• HVAC system performance
• Commissioning
• Simple to operate
• Plant maintenance
• Critical environment certification
• Duct traverses
