This product is now obsolete and has been replaced by the 9565 VELOCICALC Ventilation Meter.
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.
