AIRFLOW PRECISION AIR VELOCITY INSTRUMENTS
The AF200
offers high standards of performance and value for precision air velocity
measurements. The pitot tube method of measurement employed by the AF200
is suitable over the range 1.5m/s to 58m/s and up to +600°C. The instrument
can be corrected for temperature, static pressure, and K factor by keying
in the appropriate values. When used with the Pt100
resistance thermometer the temperature correction can is applied automatically
up to 200C. The Averaging function produces a running average from a series
of readings as they are taken. (For example at different points accross
a duct)
A full
kit is available to accompany the AF200. This includes 295mm/12” pitot
tubes, air temperature probe, instrument protective cover and sling, quick
fit pressure connectors, rubber tubing, nylon tubing and
9V PP3 battery. All this fits neatly into a custom carrying
case.
The
instrument also functions as a stand alone micro-manometer or temperature
meter.
