ENERGY AND COMFORT

VELOCICALC

Multi-Function Ventilation Meter

Series 9555

The Series 9555 are portable, hand held, Multi-Function Ventilation Test Instruments. These instruments are available with or without a differential pressure sensor and are designed to work with a wide range of plug-in probes. The probes allow users to make various measurements by simply plugging in a different probe that has the features and functions best suited for a particular application. They are designed to measure air velocity, temperature, humidity, CO and CO2. Calculations include air flow, heat flow, turbulence, wet bulb and dew point temperature.

The probes can be ordered at any time and include a data sheet with certificate of traceability. When its time for servicing, only the probe needs to be returned since all the calibration data is stored within the probe.

Pressure velocity measurements are not recommended below 1000 ft/min (5 m/s) and are best suited to velocities over 2,000 ft/min (10.00 m/s). Range can vary depending on barometric pressure.

Accuracy is a function of converting pressure to velocity. Conversion accuracy improves when actual pressure values increase.

Overpressure range = 190 in. H2O (360 mmHg, 48 kPa).
