VelociCalc Air Velocity Meter 9545 TSI

VelociCalc Air Velocity Meter 9545 TSI

Advanced Instrument for Velocity, Temperature, and Humidity Measurement

The VelociCalc® Air Velocity Meter 9545 is a high-performance, multifunctional ventilation testing instrument designed to measure and record key HVAC parameters with precision. Featuring a telescopic straight probe equipped with multiple sensors, the 9545 simultaneously measures air velocity, temperature, and relative humidity while also calculating volumetric flow, wet bulb temperature, and dew point.

This meter is ideal for professionals involved in HVAC system optimization, cleanroom validation, commissioning, and facility maintenance. Its intuitive interface allows easy operation, and the high-resolution display can show up to three measurements simultaneously, enhancing user efficiency during complex assessments.

The VelociCalc 9545 also includes powerful data logging capabilities, capable of storing more than 12,700 samples and 100 test IDs, making it ideal for ongoing monitoring and detailed reporting. The USB interface allows easy data transfer to a computer for further analysis.

This model is a top choice for critical environment certification, providing reliable measurements for duct traverses and ventilation system evaluations. A version with an articulated probe (9545-A) is also available for greater flexibility in tight spaces.
