VELOCICALC® PLUS Multi-Function Ventilation Meter 9565

The TSI VelociCalc 9565 series are portable, hand held,Multi-Function Ventilation Test Instruments. These

instruments are available with or without a differentialpressure sensor and are designed to work with a wide

range of plug-in probes. They are designed to measure airvelocity, temperature, humidity, CO and CO2.

Calculations include air flow, heat flow, turbulence, wet bulband dew point temperature. The probes can be

ordered at any time and include a data sheet with certificate oftraceability. When it is time for servicing, only

the probe needs to be returned since all the calibration data isstored within the probe.
